Cross-references to related applications

[0002] This application claims priority to U.S. Provisional Application No. 62 / 645,584, filed March 20, 2018, and is a non-provisional application of that application, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to an observation optics device having a body and a base coupled to the body. In another embodiment, the base has an optical module for a reticle. Background Technology

[0004] Rifle sights have been in use for over a century, and although the quality and functionality of these devices have improved dramatically in recent years, the core components used in their design, manufacture, and use (and the limitations of these components) remain remarkably similar to what they were 100 years ago. A rifle sight creates a magnified or unmagnified image of a scene at a distance from the shooter on the focal plane, which coincides with the aiming function or reticle. The reticle, consisting of wire or a material deposited in a pattern on a glass surface, serves as an aiming reference, corresponding to the trajectory of the attached rifle. The reticle may also include specific functions to aid the shooter in distance judgment and compensate for bullet deviations at different distances.

[0005] One challenge in the industry is designing rifle scopes that can be used for close- to medium-range shooting. Scopes of this type are required, with a minimum magnification of 1x and a maximum of 6x, 8x, or even 10x.

[0006] What is particularly difficult to achieve is a rifle scope with a first focal plane ("FFP") light-colored reticle that does not darken when your head deviates from the axis. Some rifle scopes on the market have magnifications of 1x to 6x, FFP, and daylight-colored reticles, but the reticle darkens when the user's head deviates from the axis.

[0007] Recently, new rifle scopes have been introduced to the market, featuring magnification from 1 to 8x, FFP (Free-Flash Fiber) reticles, and daylight-level reticles that barely darken when the user moves their head off-axis. However, the problem with these rifle scopes is that, in order to achieve this, they have significantly narrowed their field of view.

[0008] IMT has manufactured a reticle called a "power lamp" that solves the problem of daylight-level FFP reticles. This is because the diffraction grating process on the reticle reflects light off the pattern, causing constructive interference and thus guiding and enhancing the brightness of light deviating from the reticle pattern. This diffraction grating process is created using photolithography techniques common in the microprocessor manufacturing industry. To complete the system, IMT uses an optical module system or a special optical package mounted on the side of the reticle to guide light onto the diffraction pattern on the reticle. Throughout this disclosure, the optical module system and the optical system are interchangeable. This optical package is quite large and occupies space within the lens barrel, which is very valuable.

[0009] In rifle scopes with an FFP reticle design, the space within the scope tube at the FFP determines your field of view (FOV) potential, as well as total elevation and windage travel. This space within the scope tube can be used for travel and FOV; you can allocate or reserve space for either element.

[0010] For example, a typical 1-8x24 FFP rifle scope has an objective lens focal length of 50 mm. To determine how much lateral space (in millimeters) is needed for 1 milliradian angle adjustment knob travel (MRAD), divide the objective lens focal length by 1000. In this case, 50mm / 1000 (MRAD / mm) = 0.050mm. This means that 1 MRAD of angle adjustment knob travel or FOV occupies 0.050mm of lateral space inside the scope tube. These types of rifle scopes typically require approximately 29 MRAD of total travel to allow the end user sufficient space to zero the scope on their rifle.

[0011] The best modern optics are 1-8x or 1-10x, typically with a field of view (FOV) of approximately 22° (approximately 384 MRAD) at 1x. If we add the total travel and lateral space required for the FOV of the best optical designs on the market, the total lateral space equals ((29 + 384) * 0.050) = 20.65 mm. Now, when you start adding the mechanical equipment needed to house the reticle, there isn't much space available for any other purpose.

[0012] A typical 1-8x or 1-10x FFP scope uses an industry-standard 34mm barrel, and for strength reasons, its wall thickness is likely 2mm. This means the inner diameter is likely around 30mm. If you subtract the space for the 29 MRAD travel and the FOV (20.65mm) for the 384 MRAD, you're left with only 9.35mm for the reticle. This space is easily used up just for the reticle to hold the reticle. Now, if you try to implement an optical module system (such as the IMT "Powerlight" module), there isn't enough space to accommodate everything. Therefore, current rifle scope manufacturers on the market simply trade space for FOV to fit the IMT "Powerlight" module.

[0013] Therefore, there remains a need for an observation optics that can have a daytime brightness level reticle and make no compromises in other characteristics such as field of view. The apparatus, system, and method disclosed herein address all these shortcomings in an innovative way. Summary of the Invention

[0062] I. Definition The numerical ranges in this disclosure are approximate and therefore may include values ​​outside the range unless otherwise indicated. A numerical range includes all values ​​from, including, the upper and lower limits, in increments of one unit, provided there is at least a two-unit interval between any lower and higher value. For example, if the composition, physical, or other property (e.g., molecular weight, viscosity, etc.) is 100 to 1,000, it means that all individual values ​​(e.g., 100, 101, 102, etc.) and subranges (e.g., 100 to 144, 155 to 170, 197 to 200, etc.) are explicitly listed. For ranges containing values ​​less than 1 or decimals greater than 1 (e.g., 1.1, 1.5, etc.), one unit is considered to be 0.0001, 0.001, 0.01, or 0.1, as appropriate. For ranges containing a single digit less than 10 (e.g., 1 to 5), one unit is generally considered to be 0.1. These are merely examples of specific intentions, and all possible combinations of values ​​between the listed minimum and maximum values ​​should be considered as expressly stated in this disclosure.

Similarly, the term “and / or” used in phrases such as “A, B and / or C” is intended to cover each of the following embodiments: A, B and C; A, B or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).

[0064] As used herein, an "image-straightening sleeve" is a protrusion extending from an image-straightening lens mount that engages with a slot in an image-straightening lens tube and / or a cam-straightening lens tube, or for similar purposes. The image-straightening sleeve may be integral with the mount or removable.

[0065] As used in this article, "positive lens tube" is any structure or device having an opening to receive a positive lens mount.

[0066] As used herein, "firearm" refers to a portable weapon that fires one or more projectiles, typically propelled by an explosive force. As used herein, the term "firearm" includes pistols, rifles, shotguns, carbines, automatic weapons, semi-automatic weapons, machine guns, submachine guns, automatic rifles, and assault rifles.

[0067] As used herein, the term "optical module" refers to a module used to direct light onto a reticle. In one embodiment, an optical system is used to direct light onto a diffraction pattern on the reticle.

[0068] As used herein, the term "observation optics" refers to a device used by a shooter or observer to select, identify, or monitor a target. "Observation optics" may rely on visual observation of the target, or, for example, on infrared (IR), ultraviolet (UV), radar, thermal, microwave, or magnetic imaging, radiation (including X-rays, gamma rays, isotopic radiation, and particle radiation), night vision, vibration receivers (including ultrasound, acoustic pulses, sonar, seismic vibrations, and magnetic resonance), gravity receivers, broadcast frequencies (including radio waves, television, and cellular receivers), or other images of the target. The target image presented to the shooter by the "observation optics" device may remain unchanged, or may be enhanced, for example, by magnification, enlargement, subtraction, superposition, filtering, stabilization, template matching, or other means. The target selected, identified, or monitored by the "observation optics" may be within the shooter's line of sight, tangent to the shooter's line of sight, or the shooter's line of sight may be obstructed when the target acquisition device presents a focused image of the target to the shooter. Images of a target acquired by an "observation optics" can be, for example, analog or digital, and can be shared, stored, archived, or transmitted within a network of one or more shooters and observers, for example using protocols such as HTML, SML, SOAP, X.25, SNA, Bluetooth™, Serial, USB, or other suitable image distribution methods, via, for example, video, physical cable or cabling, IR, radio waves, cellular connections, laser pulses, optics, 802.1lb, or other wireless transmissions.

[0071] II. Observing Optical Devices Figure 1A The traditional design of a rifle scope is shown, which is a typical example of an observation optics. Figure 1B An exemplary observation optics 10 according to an embodiment of the present disclosure is shown. Specifically, Figure 1B A rifle scope is shown. More specifically, the rifle scope 10 has a body 38 surrounding a movable optics element 15. The body 38 is an elongated tube that tapers gradually from a larger opening at its front 40 to a smaller opening at its rear 42. An eyepiece 56 is attached to the rear of the scope body, and an objective lens 54 is attached to the front of the scope body. The central axis of the movable optics element defines the optical axis 44 of the rifle scope.

[0072] The elevation adjustment knob 12 and the wind direction adjustment knob 48 are two dials, typically located in the center of the outer side of the main body 38. They are marked with increments of marking 20 on their periphery 11 and are used to adjust the elevation angle and wind direction of the movable optical element to change the point of impact. These dials protrude from the adjustment knob housing 50. The adjustment knobs are arranged such that the rotation axis 46 of the elevation adjustment knob is perpendicular to the rotation axis 52 of the wind direction adjustment knob.

[0073] Figure 1C It shows Figure 1B A cross-sectional view of an aiming device, which has the basic components of an optical system 14 and movable optical elements 15. (Example) Figure 1C As shown, the optical system 14 includes an objective lens system 16, an image erecting system 25, and an eyepiece system 18. Figure 1C A rifle scope with a main body 38 is shown, but the optical system 14 can also be used with other types of aiming devices. An image-establishing system 25 can be included within the movable optical element 15. Figure 1C The movable optical element 15 also includes a light collector 22, a first focal plane reticle 55, and a second focal plane reticle 57. In use, adjusting the adjustment knob assembly 28 and the adjustment knob screw 29 causes adjustment of the movable optical element 15.

[0074] The movable optics 15 are adjusted by rotating the adjustment knob assembly 28 with one or more clicks. As the adjustment knob is rotated, the adjustment knob screw 29 moves in and out of the scope, which in turn pushes the image tube. The image tube is spring-biased, so when the adjustment knob screw is adjusted, it positions the image tube against the bottom surface of the adjustment knob screw. The image tube provides a smaller view of the entire image. When the image tube is adjusted, the position of the reticle is modified relative to the image.

[0075] The reticle is a circular, planar, or flat transparent panel or disk mounted within the scope body in a relationship perpendicular to the optical axis or the line of sight passing through the scope, and located between the objective lens element 54 and the image-establishing lens element, typically at the location considered the front focal plane of the optical system within the housing. In one embodiment, the reticle includes finely etched lines or fine line markings, including a central vertical fine line and a central horizontal fine line, which intersect orthogonally or perpendicularly at a central point.

[0076] In one embodiment, such as Figure 1DAs shown, the observation optics may have a parallax adjustment knob 70 or a focus knob. Parallax occurs when the optical plane of the target's image is not coplanar with the optical plane of the reticle's image. Due to the offset between the two optical planes, the reticle may appear to move relative to the target as the shooter's eye moves around the center of the reticle. This parallax error can cause the point of impact to shift relative to the launch point. By allowing the optical system to be adjusted to display the target's image and the reticle's image on the same optical plane, parallax adjustment of the observation optics allows the shooter to eliminate optical errors at different distances. Parallax compensation does not change the focus of the reticle or the image; it simply moves the planes in focus of the two objects so that they share the same plane (coincide).

[0077] like Figure 1D As shown, the observation optics may have a side wheel mounted on a rotatable parallax adjustment knob 70. The larger diameter of this side wheel provides more space for applying markings such as range markers and makes it easier for the shooter to rotate and read them during use. The larger diameter of the side wheel improves the accuracy and resolution of the rangefinder markings.

[0078] Figure 1E A close-up view of the optical system 14 is shown in cross-section, illustrating how light travels through the optical system 14. The optical system 14 may have additional optical components such as a light condenser 22, and it is well known in the art that some components such as the objective lens system 16, the image erecting system 25, and the eyepiece system 18 may themselves have multiple components or lenses.

[0079] In one embodiment, the observation optics may have a focusing unit having one or more adjustable lenses for providing parallax adjustment. In one embodiment, the one or more adjustable lenses are a single or parallax lens.

[0080] In one embodiment, a focusing lens is located between the eyepiece and the objective lens. The relative distance between the focusing lens and the objective lens is adjustable to provide parallax adjustment. Additionally, an erecting lens is located between the eyepiece and the focusing lens. The relative distance between the erecting lens and the objective lens is adjustable to provide magnification adjustment.

[0085] A. Main Body In one embodiment, the body is in the shape of an elongated tube that tapers from a larger opening at its front to a smaller opening at its rear, with an eyepiece attached to the rear of the elongated tube and an objective lens attached to the front of the elongated tube. In one embodiment, the first housing is the body of a rifle scope.

[0086] In one embodiment, the main body has an observation input terminal and an observation output terminal, which can be positioned along the observation optical axis 54 ( Figure 1B The viewer can be aligned and can be in a straight line. It can pass through the viewing input, along the viewing direct-view optics, and exit from the viewing output, allowing the user to directly view the object or target. The main body can include an objective lens or lens assembly at the viewing input. A first focal plane reticle can be positioned and spaced from the objective lens assembly along the viewing optical axis A.

[0087] In one embodiment, the image or image reversal lens assembly can be positioned along the observation optical axis A from the first focal plane reticle and spaced backward. An image-reversing tube with an image-reversing system is located within the body between the objective and eyepiece to invert the image. This ensures the image is correctly oriented for land viewing. The image-reversing system is typically contained within the image-reversing tube.

[0088] A reversing lens assembly or imaging system may include one or more lenses spaced apart from each other. An imaging system may include one or more movable optical elements, such as a focusing lens movable along its optical axis to adjust the image focus, and a magnifying lens movable along its optical axis to optically magnify the image at the back focal plane, thus making the target appear closer than it actually is. Typically, an imaging assembly includes mechanical, electromechanical, or photoelectric systems for driving the coordinated movement of both the focusing lens and the magnifying lens, one or more power-varying lens elements, to provide a continuously variable magnification range across which the imaging assembly produces a focused, upright image of a distant target at the back focal plane.

[0089] Variable magnification can be achieved by providing a mechanism for adjusting the position of the positive lenses relative to each other within the positive image tube. This is typically accomplished using a cam tube tightly surrounding the positive image tube. Each positive lens (or lens group) is mounted in a positive lens mount that slides within the positive image tube. An positive sleeve attached to the positive lens mount slides in a straight slot on the body of the positive image tube to maintain the orientation of the positive lens. The positive sleeve also engages with angled or curved slots on the cam tube. Rotating the cam tube causes the positive lens mount to move longitudinally within the tube, thereby changing the magnification. Each positive lens has its own slot in the cam tube, and the configuration of these slots determines the amount and rate of change of magnification when the cam tube is rotated.

[0090] The aperture in the second focal plane can be positioned and rearwardly spaced from the image reversal assembly along the observation optical axis A. The eyepiece assembly can be positioned and rearwardly spaced from the aperture in the second focal plane along the observation optical axis A at the eyepiece. The eyepiece assembly may include one or more lenses spaced apart from each other. In some embodiments, the observation optical axis A and the direct observation optics can be folded.

[0091] B. Base In one embodiment, the second housing is coupled to the first housing, and the second housing contains an optical module or optical system for directing light to the reticle. In one embodiment, the second housing is a base coupled to a portion of the body of the observation optics. In one embodiment, the base is separable from the body of the observation optics. U.S. Patent Nos. 10,180,565, 16 / 246,689, and 16 / 247,089 describe a typical base that can accommodate an optical module for the reticle.

[0092] In a representative embodiment, Figure 2A side view of a rifle scope 200 having a body 210 and a base 220 is shown. In one embodiment, the base 220 is detachable from the body 210. The base 220 is attached to one end of the scope body near the magnification ring 212 and to the other end of the scope body near the objective lens assembly 214. In one embodiment, the body 210 and the base 220 are made of the same material. In another embodiment, the scope body and the base are made of different materials.

[0093] In one embodiment, the base 220 is approximately the length of the positive image tube of the main body.

[0094] Figure 3 This is a representative schematic diagram of a rifle scope, showing the body 210 separated from the base 220 for illustrative purposes. The base 220 is attached to the bottom of the body 210. The base 220 has space for accommodating the optical module for the reticle and space for additional components.

[0095] In one embodiment, the base is not an image stabilization device. In one embodiment, the length of the base is 35% to 70% of the length of the rifle scope body to which the base is attached. In yet another embodiment, the base having an optical module system is 40% to 65% of the length of the rifle scope body to which the base is attached. In still another embodiment, the base having an optical module for a reticle is no more than 65% of the length of the rifle scope body to which the base is attached.

[0096] In one embodiment, the body of the rifle scope is approximately 2.5 times the length of the base having the optical module for the reticle. In another embodiment, the length of the body is 1.5 to 2.5 times the length of the base having the optical module for the reticle. In yet another embodiment, the body is at least 1.5 times the length of the base having the optical module for the reticle.

[0097] like Figure 2 As shown, the base 220 can be screwed onto the scope body 210 of a rifle scope to form a fully enclosed and integrated system. The base 220 can then be directly attached to the firearm without the need for a traditional rifle scope ring.

[0098] In one embodiment, an observation optics device can be coupled to a firearm without a conventional rifle scope ring. The observation optics device has a body and a base, the base being coupled to the body and having an optical module for a reticle. In another embodiment, the observation optics device has a body and a base, the base being coupled to the body and having an optical module for a reticle, wherein the base has a mounting rail on its underside.

[0099] In one embodiment, the base for the observation optics may include a mounting rail for mounting to a desired firearm, equipment, or device, and may have an adjustment mechanism including an elevation adjustment swivel for adjusting the elevation position of the optics. A lateral adjustment mechanism is also typically provided for side adjustment. The adjustment mechanism may be covered by a protective shield.

[0100] In one embodiment, the top side of the base is connected to the bottom side of the body of the observation optics, and the bottom side of the base has a mounting rail. In another embodiment, the top side of the base is connected to a transverse slit in the bottom side of the body of the observation optics.

[0101] 1. Optical module In one embodiment, the observation optics has a body and a base coupled to the body, wherein the base has an optical module for the reticle. In another embodiment, the observation optics has a body and a base coupled to the body, wherein the base has an optical module for providing illumination to the reticle.

[0102] In one embodiment, the observation optics has a body and a base coupled to the body, wherein the base has at least a portion of an optical module for the reticle. In another embodiment, the observation optics has a body and a base coupled to the body, wherein the base has at least a portion of an optical module for providing illumination to the reticle.

[0103] In one embodiment, the complete optical module system is located in the base. In another embodiment, a portion of the optical module system is located in the base, while a portion of the optical module system is located in the body.

[0104] In one embodiment, approximately 50% to approximately 75% of the optical module system is located in the base. In another embodiment, approximately 75% to approximately 95% of the optical module system is located in the base.

[0105] In yet another embodiment, at least 40% of the optical module system is located in the base.

[0106] In one embodiment, the observation optics has a body and a base coupled to the body, wherein the base has an optical module for guiding light to a reticle. In one embodiment, light is guided to a diffraction pattern on the reticle. In one embodiment, the optical module is directly or indirectly coupled to the reticle. In yet another embodiment, the optical module guides light to the reticle but is not coupled to the reticle. In one embodiment, the reticle may be in an FFP or an SFP, or both.

[0107] In one embodiment, the optical module is coupled to the outer periphery of the reticle. In one embodiment, the reticle is a first focal plane reticle. In one embodiment, the reticle is located within the body of the observation optics.

[0108] Figure 4 This is a schematic diagram of a reticle system 400 having a reticle 410 and an optical module 420. The optical module is shown at the 6:00 position on the reticle. The optical module 420 is mounted in a base that is connected to the main body of the observation optics.

[0109] Figure 5 This is a schematic diagram of a reticle system with an optical module 420, which is attached to the 12:00 position on the outer periphery of the reticle 410. In some embodiments, the optical module for the reticle may be located in the main body, but the battery, power supply, and any associated electronics may be located in a base connected to the main body of the observation optics.

[0110] Figure 6A and 6B A representative illustration of a reticle 410 with an optical module 420 is provided. Modules that guide light to the diffraction pattern on the reticle can be placed on the outer periphery of the reticle at approximately 1:00, 2:00, 3:00, 4:00, 5:00, 6:00, 7:00, 8:00, 9:00, 10:00, 11:00, or 12:00.

[0111] In one embodiment, the optical module is placed on the reticle from approximately 3:00 to approximately 6:00. In another embodiment, the optical module is placed on the reticle from approximately 3:00 to approximately 9:00. In yet another embodiment, the optical module is placed on the reticle from approximately 3:00 to approximately 12:00.

[0112] In one embodiment, the optical module is placed on the reticle from approximately 5:00 to approximately 7:00. In another embodiment, the optical module is placed on the reticle from approximately 5:00 to approximately 9:00.

[0113] In one embodiment, the optical module is placed on the reticle from approximately 4:00 to approximately 6:00. In another embodiment, the optical module is placed on the reticle from approximately 4:00 to approximately 8:00. In yet another embodiment, the optical module is placed on the reticle from approximately 4:00 to approximately 12:00.

[0114] In another embodiment, the optical system is positioned on the reticle from approximately 6:00 to approximately 9:00. In one embodiment, the optical module is positioned on the reticle from approximately 6:00 to approximately 12:00. In another embodiment, the optical module is positioned on the reticle from approximately 6:00 to approximately 10:00.

[0115] In one embodiment, the reticle is located at a first focal plane in the body of the observation optics, and the optical system is located in a base connected to the body of the observation optics.

[0116] In one embodiment, the base may have one or more optical module systems, including two, three, four, five or more optical module systems.

[0117] In one embodiment, the reticle is an IMT Power Light reticle, including but not limited to IMT PowerLight 22 / 25 or IMT Power Light 28. Unbound by any particular theory, to illuminate the structure, light radiation is incident on the substrate from the side and impacts the illuminated structure through total internal reflection. For this purpose, IMT provides two technical solutions: (1) diffraction structures; (2) etching and filling.

[0118] For diffractive structures, a grating is etched into the substrate. Due to diffraction on the grating, the incident radiation reaches the eye. Diffractive reticles are characterized by high light output, and therefore can be used even in very bright environments.

[0119] For etching and filling, a structure is etched onto a substrate, and dye is filled into the structure. The dye disperses incident radiation toward the eye. Etching and filling structures offer an alternative for applications where brightness and resolution are less critical.

[0120] 2. Power supply In one embodiment, the base connected to the body of the observation optics has a power supply system. In another embodiment, the base of the observation optics has a cavity. The battery cavity may be integrated into the base, which is connected to the body of the observation optics.

[0121] Figure 7 This is a representative schematic diagram of a base 220 with a battery compartment 705, wherein the base 220 is connected to the body 210 of a rifle scope 700. (As shown) Figure 7 and Figure 8 As shown, the battery cavity 705 extends from each side of the base to encapsulate a battery, including but not limited to a CR123 battery. Compared to smaller batteries or coin-sized batteries, the CR123 battery has higher power capacity and discharge performance.

[0122] In one embodiment, the battery cavity 705 is integrated with the base 220, so only a battery cover is needed to protect the battery from environmental influences. No additional sealing is required.

[0123] In one embodiment, the battery cavity 705 in the base 220 is positioned closer to the objective lens assembly 710 of the body 210 of the observation optics than to the eyepiece assembly.

[0124] Figure 9 This is a representative illustration of the battery compartment 705 integrated into the base 220. In one embodiment, the compartment 705 is designed to be inserted first into the front side of the battery, and has a mechanical stop at the bottom of the battery compartment to prevent improper installation and handling of the battery.

[0125] In one embodiment, the integrated battery compartment 705 can use the same gasket as the base 220 of the rifle scope body 210. Since a separate battery compartment is not required, this provides a more reliable seal and eliminates mechanical devices. Secondly, because the battery compartment is integrated into the base, there are no mechanical devices for securing the battery compartment. This reduces the need for any mechanical interfaces for securing the battery compartment. Because no mechanical locking mechanism is required for the battery compartment, the integrated battery compartment reduces the points of failure associated with conventional battery compartments.

[0126] The integrated battery compartment eliminates any obstacles for the user. Located beneath the observation optics, it operates outside the reach of the adjustments and knobs found on traditional observation optics. This integrated battery compartment is a significant advancement as it provides the necessary space to accommodate a larger battery.

[0127] 3. Picatinny Mount In one embodiment, this disclosure relates to an observation optics having a body and a base, the base having a battery compartment and a Picatinny mount connectable to the battery compartment. In one embodiment, a movable Picatinny mount is attached to a protruding battery compartment that is incorporated into the base, which is connected to the body of a rifle scope.

[0128] Figures 10 to 12 This is a representative schematic diagram of a rifle scope having a body 210 and a base 220 attached to the body 210, the base having a battery compartment 705 that can be attached to a Picatinny mount 1005. In one embodiment, the Picatinny mount 1005 is aligned with the battery compartment 705 and secured with fasteners.

[0129] By attaching the mounting base 1005 to the battery compartment 705 of the base 220, the materials required for manufacturing the cavity 705 for the battery are utilized. This eliminates the need to obtain any additional materials from the base, thereby making the observation optics lighter and less invasive.

[0130] In one embodiment, the mount is positioned toward the objective lens of the adjustment knob and parallax knob so as not to affect the user's ability to adjust the rifle scope. Furthermore, the top ring is removable, allowing for easy attachment of accessory devices, such as laser rangefinders. By utilizing the Picatinny mount disclosed herein, no additional structural support from the top of the ring is required because the integrated base secures the rifle scope.

[0131] In one embodiment, the mount includes a cantilevered Picatinny rail that extends forward toward the objective lens of the rifle scope. This allows the laser rangefinder mounted on the weapon to be positioned directly on the bell jar of the rifle scope. This mounting method reduces bullet impact deviation and improves the accuracy of the rangefinder. By reducing variables that could affect the rangefinder's ability to acquire the desired target, the likelihood of bullet impact deviation is reduced.

[0132] 4. Data Port In one embodiment, this disclosure relates to an observation optics having a body and a base, the base having an optical system for guiding light onto a diffraction pattern on a reticle, wherein the base has an axially oriented data port for interfacing with auxiliary devices, including but not limited to remote control switches and laser rangefinders.

[0133] Figure 13 This is a representative schematic diagram of a rifle scope 1300, which has a body 210 and a base 220, the base 220 having an axially oriented data port 1305. In one embodiment, the observation optics may have one axially oriented data port. In another embodiment, the observation optics may have two or more axially oriented data ports.

[0134] By utilizing the axially oriented data port 1305, the top-down profile of the entire observation optics is minimized, thereby increasing the robustness of the mounted system and its connections.

[0135] Figure 14 This is a representative example of a rifle scope, which has a body and a base to which the body is attached and has an optical system for guiding light onto a diffraction pattern on a reticle. The base may have one or more compartments for power supply. The rifle scope may have a Picatinny mount.
