[0002] This application relates to the field of optical viewing devices and more specifically to devices for lighting and viewing objects.RELATED APPLICATIONS

[0003] BACKGROUND OF THE INVENTION

[0004] Head-bome or wearable eyewear utilizing telescopic lenses provides a practitioner with a magnified view of an area that the practitioner is viewing. Whether this is a patient’s mouth, as in the case of a dentist, or in a body cavity, as in the case of a surgeon, the magnified view enables the practitioner to both see details that may not be viewable without the telescopic lens and provide more precise location of their instruments.

[0005] Such telescopic or magnification devices (i.e., loupes) typically are designed to operate in conjunction with a lighting system to provide an enlarged view of an object a known distance from the user. In many cases, the lighting systems may have overhead lighting that must be positioned to avoid the user casting a shadow onto the working area. In other cases, the lighting system may be attached to the user but must be adjusted to project the light onto the area being viewed by the loupe.

[0006] Hence, there is a need in the industry for a system that enables the light to be presented directly onto the viewing area without causing any shadowing or having to be adjusted by the user.SUMMARY OF THE INVENTION

[0007] Disclosed is an integrated lighted loupe system that may be incorporated into eyewear that provides for the concurrent viewing and lighting of an object.

[0008] Disclosed is a loupe system that may utilize an on-board light that may be projected onto an area viewed by the loupe system.

[0034] It is to be understood that the figures, which are not draw n to scale, and descriptions of the present invention described herein have been simplified to illustrate the elements that are relevant for a clear understanding of the present invention, while eliminating, for purposes of clarity, many other elements. However, because these omitted elements are well- known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements are not provided herein. The disclosure, herein, is directed also to variations and modifications known to those skilled in the art.DETAILED DESCRIPTION OF THE INVENTION.

[0035] As used herein, the terms "comprises", "comprising", "includes", "including", "has", "having", or any other variation thereof, are intended to cover non-exclusive inclusions. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. In addition, unless expressly stated to the contrary, the term "of refers to an inclusive "or" and not to an exclusive "or". For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present); A is false (or not present) and B is true (or present); and both A and B are true (or present).

[0036] The terms "a" or "an" as used herein are to describe elements and components of the invention. This is done for convenience to the reader and to provide a general sense of the invention. The use of these terms in the description, herein, should be read and understood to include one or at least one. In addition, the singular also includes the plural unless indicated to the contrary. For example, reference to a composition containing "a compound" includes one or more compounds. As used in this specification and the appended claims, the term "or" is generally employed in its sense including "and / or" unless the content clearly dictates otherwise.Serial No.: TBD Filing Date: TBD For: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104 Attn.: C. A. Giordano, Reg. No.: 41780 August2024 August 2025

[0037] All numeric values are herein assumed to be modified by the term "about," whether or not explicitly indicated. The term "about" generally refers to a range of numbers that one skill in the art would consider equivalent to the recited value (i.e., having the same function or result). In any instance, the terms "about" may include numbers that are rounded (or lowered) to the nearest significant figure.

[0038] Although the terms “perpendicular” and “orthogonal” are used herein to describe a relationship between two elements, it would be understood and recognized by those skilled in the art that the terms “perpendicular” and “orthogonal” are not used in the mathematical sense (i.e., precisely ninety (90) degrees). But rather in the manufacturing sense wherein a tolerance value is imposed. Such tolerance values may be considered, for example, + / - 1 degree. Thus, the terms “substantially perpendicular, “substantially “orthogonal,” “substantially center,” etc. should be understood as being used to represent a relationship between elements in the manufacturing sense (i.e., within known tolerance values).

[0039] FIG. 1 illustrates an exploded perspective view of a first aspect of a first exemplary embodiment of a telescopic loupe with an integrated lighting system in accordance with the principles of the invention.

[0040] In this illustrated embodiment, lighted loupe 100 comprises housing 110 (comprising an upper housing element 110a and a lower housing element 110b). where upper housing 110a and lower housing 110 may be j oined together with an adhesive to retain the illustrated elements in place.

[0041] Further illustrated are objective lens 120, positioned within a distal end of housing 110 and an eye-lens housing 130 insertable within a proximal end 161 of housing 110. Eyelens 135. insertable into eye-lens housing 130. creates a magnification device with respect to objective lens 120, wherein the level of magnification of loupe 100 may be determined based on the optical characteristics of objective lens 120 and eye-lens 135, and the distance separating objective lens 120 and eye-lens 135. In addition, the combination of objective lens 120 and eye-lens 135 forms a first optical axis 137 through which light 190 from an object (not shown) is viewed by loupe 100.

[0042] Further illustrated is lighting element 140 containing therein at least one lighting source (not shown) configured to emit light 195 in one or more light wavelength ranges. Lighting element 140 is positioned offset from (and illustrated as being substantially perpendicular) to optical axis 137 formed by objective lens 120 and eye-lens 135.Serial No.: TBDFiling Date: TBDFor: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104Attn.: C. A. Giordano, Reg. No.: 41780August2024August 2025

[0043] Light 195 emitted by lighting element 140 travels along axis 145. wherein axis 145 is offset from to optical axis 135.

[0044] Within housing 110 is positioned light director 150, which may comprise a beam splitter including a dichroic mirror surface. Alternatively, light director 150 may comprise a plate beam splitter comprising a dichroic mirror surface. In still in another aspect, light director 150 may comprise a Pelican beam, a block beam splitter and similar devices that provide for a partially reflective / partially transmissive of light along more than axis.

[0045] Dichroic mirror surfaces, as is known in the art, are mirror assemblies with different reflection or transmission properties at two different wavelengths (or wavelength regions). For example, a dichroic mirror may be designed to transmit approximately 90% of an incident light at most wavelengths (except at a desired wavelength) and reflect around 10% (Including the desired w avelength) of the light from the mirrored surface. Dichroic mirrors, also referred to as thin-fdm interference filters, rely on precise coatings to control the transmission and reflection of specific wavelengths of light. These coatings are engineered to create constructive interference for the wavelengths that need to be transmitted and destructive interference for those that need to be reflected.

[0046] In one aspect a mirrored surface may be formulated to provide a high transmission rate (e.g., 90%) across most wavelengths and a lower reflection rate (e.g., 10%) at select wavelengths with appropriate design of the multilayer coatings, which may be tailored (or selected) to have a notch around selected wavelengths. For instance, at the desired wavelength, the dichroic mirror may reflect more light and transmit less.

[0047] Light director 150 may be positioned at the intersection of optical axis 135 and axis 145 such that light entering objective lens along optical axis 137 passes through light director 150 while light emitted by lighting element 140 is reflected toward objective lens 120. Hence, emitted light is projected directly onto the area or object being viewed.

[0048] In accordance with an aspect of the invention, excitation light element 140 may emit a white light. Alternatively, excitation light element 140 may emit light in one or more of a non-visible wavelength range (e.g., infra-red, ultra-violet) or selected wavelength bands associated with visible light (e.g., blue light 400-450 nanometers (nm), green light 500-560 nm, red light 700-780nm, etc.). In still a further aspect of the invention, excitation filter 170 may be incorporated into lighting element 140 to limit the wavelength range emitted by the one or more lighting sources w ithin lighting element 140. For example, excitation filter 170Serial No.: TBD Filing Date: TBD For: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104 Attn.: C. A. Giordano, Reg. No.: 41780 August2024 August 2025 may limit the wavelength band of a white light lighting source to an excitation light within a blue wavelength range. Alternatively, excitation filter 170 may limit the wavelength range of a blue lighting source to a narrow wavelength band (e.g., 400-430 nm).

[0049] In still a further aspect of the invention, an emission filter 160 may be incorporated into a proximal end 161 of housing 110. wherein emission filter 160 is configured to limit a wavelength range of a light emitted or reflected by an object (not shown) passing through light director 150 along optical axis 137. In one aspect of the invention, the optical characteristics of emission filter 160 may be selected based on an expected wavelength range of light emitted or reflected by an object passing through light director 150. Alternatively, the optical characteristics of emission filter 160 may be selected to view a desired wavelength range.

[0050] In still a further aspect of the invention, a working distance lens 122 may be incorporated into objective lens 120. Working distance lens 122 is configured to define a distance from objective lens 120.

[0051] FIG. 2 illustrates an exploded perspective view of a second aspect of the first exemplary embodiment of a magnification device or telescopic loupe with an integrated through-the-lens lighting system shown in FIG. 1. In this illustrated embodiment, telescopic loupe with integrated lighting element 200 comprises a housing 110 comprising objective lens 120, eye-lens 135 and lighting source 140 as disclosed with regard to FIG. 1. Further illustrated is light lens (referred to a light lens 235), positioned along axis 145. In accordance with this aspect of the invention, light lens 235 is configured to focus and / or concentrate the excitation light emitted by lighting element 140. Although light lens 235 is shown in FIG. 2, it would be recognized by those skilled in the art that the incorporation of light lens 235 into the configurations shown is an optional configuration as the focusing or concentration of the excitation light is not a necessary element of the invention disclosed. In addition, in those cases where the excitation light is to be focused or concentrated, it would be recognized that light lens 235 may be a separate element (as shown) or may be incorporated into lighting element 140. Although light lens 235 is depicted as having a same configuration as that of eye-lens 135, it would be recognized that the optical characteristics (e.g., lens, lens power, etc.) may be the same or different than the optical characteristics of eye-lens 135.Serial No.: TBDFiling Date: TBDFor: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104Attn.: C. A. Giordano, Reg. No.: 41780August2024August 2025

[0052] FIG. 3 illustrates a side view of a first aspect of a second exemplary embodiment of the telescopic loupe with an integrated through-the-lens lighting system in accordance with the principles of the invention.

[0053] In this illustrated view, objective lens 120 and eye-lens lens assembly 135 contained within housing 110. Further illustrated is light director 150 positioned along optical axis 137 in a manner to direct light emitted by lighting element 140 toward objective lens 120. In this illustrated aspect of the invention, light director 150 is represented as a dichroic plate beam splitter configured to reflect light emitted by lighting element 140 toward objective lens 120 while allowing light entering objective lens 120 (i.e., emission light) to be directed along optical axis 137 toward eye-lens 135.

[0054] Although eye-lens 135 was shown in FIGs. 1 and 2 as comprising a single element, it would be understood by those skilled in the art that eye-lens 135 (and objective lens 120) may comprise one or more lenses based on the required or desired optical characteristics (e.g., correct chromic aberration or prescriptive lens correction). In another example, a desired optical focal length may determine the number of lenses needed within either the eyelens 135 and / or the objective lens 120. In the illustrated aspect of the invention, working distance lens 122 is shown separate from objective 120.

[0055] In accordance with the telescopic lens configuration shown prism assembly 310 is introduced in the optical path 137 between objective lens 120 and eye-lens 135. As is known in the art, light 190 entering prism assembly 310 is reflected by surfaces 311, 312, 313 314 and 315 such that light 190 exits prism assembly 310 substantially parallel to optical axis 190.

[0056] Prism assembly 310 provides for the inversion of the images viewed through objective lens 120. The viewed image is inverted as the positive optical characteristics of eyelens 135 renders an image that is upside-down. In one aspect of the invention, prism assembly 310 may comprise a Schmidt-P echan roof prism assembly.

[0057] Although a Schmidt-Pechan roof prism assembly is shown, it would be recognized that other types of image inversion prism assemblies may comprise prism assembly 310 without altering the scope of the invention claimed.

[0058] FIG. 4 illustrates a side view of a second aspect of the second exemplary7embodiment of the telescopic loupe with an integrated through-the-lens system shown in FIG. 3. In this illustrated view; which is similar to the configuration shown in FIG. 3, an light lens 235. isSerial No.: TBD Filing Date: TBD For: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104 Attn.: C. A. Giordano, Reg. No.: 41780 August2024 August 2025 incorporated into the optical path 145 along which lighting element 140 emits light. Similar to the discussion regarding the light lens 235 made in FIG. 2, light lens 235 creates a magnification device between light lens 235 and objective lens 120, which focuses or narrows the light beam of the light emitted by lighting element 140.[00591 As the configuration shown in FIG 4 is substantially the same as that shown in FIG. 3, no further discussion is believed necessary for one skilled in the art to understand the principles and operation of the configuration shown.

[0060] FIG. 5A illustrates a perspective view of the exemplary embodiment of the telescopic loupe with integrated through-the-lens lighting system shown in FIGs. 1-4.

[0061] As shown, a telescopic loupe (configured as a Galilean telescopic loupe (i.e., FIGs. 1, 2) or a Keplerian telescopic loupe (FIGs. 3, 4) may include an integrated lighting element 140 that provides light directly onto an object being viewed through the telescopic loupe.

[0062] FIG. 5B illustrates a front view of the telescopic loupe with integrated through-the- lens lighting system shown in FIGs. 1-4.

[0063] In this illustrated front view lighting element 140 is offset from (and shown positioned substantially perpendicular to) housing 110, wherein optical axis 145 passes through lighting element 140. Optical axis 137 extending into the plane of the paper on which the drawing is shown is substantially centered within objective lens 120.

[0064] FIG. 5C illustrates a top view of the telescopic loupe with integrated through-the-lens lighting system shown in FIGs. 1-4.

[0065] In this illustrated top view7, optical axis 145 is shown as being positioned offset from (and illustrated as substantially perpendicular to) optical axis 137.

[0066] Although, lighting element 140 has been shown to be positioned substantially perpendicular (i.e., within known engineering tolerances) to housing 110, it would be recognized by those skilled in the art that lighting element 140 may be positioned at a different angle (i.e., an offset angle), by the proper adjustment or orientation of splitter 150 within housing 110. Hence, discussion has been made with regard to a substantially perpendicular orientation, or offset, of lighting element 140 with respect to housing 110, it would be understood that the orientation of lighting element 140 with regard to housing 110 may be altered (i.e., non-perpendicular) without altering the scope of the invention claimed.

[0067] FIG. 6 illustrates an exploded perspective view of a first exemplary embodiment of a lighting element 140 shown in FIGs. 1-5C.Serial No.: TBDFiling Date: TBDFor: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104Attn.: C. A. Giordano, Reg. No.: 41780August2024August 2025

[0068] In this exemplary embodiment, lighting element 140 comprises housing 610 including, therein, a lighting source 612, substantially centered on a printed circuit board (PCB) 611 retained on base 615 within housing 610. As would be known in the art, lighting source 612 may comprise a single light source or an array of light sources (e.g., light emitting diodes) arranged to emit light. Lighting source(s) 612 may represent a light emitting diode that may be of a laser or non-lasing variety.

[0069] Printed circuit board (PCB) 611 includes electrical / electronic components and / or circuitry7that controls the operation of lighting source 612 (e.g., turn on / off, change intensity). Printed circuit board 611 may comprise one or more electronic components such as resistors, capacitors, inductors, integrated circuits, microprocessor and / or specialized integrated circuitry (e.g., ASIC, FPGA) that may be used to control the operation of lighting source 612. As electronic components are well-known in the art, a detailed discussion of the operation of these components is not believed necessary to understand the principles and operation of the invention claimed.

[0070] In one aspect of the invention, lighting source 675 may include aperture holder (or plate) 620 and aperture 630, including substantially centered aperture holder passthrough 625 and aperture passthrough 635, respectively, through which light from lighting source 612 maypass. Aperture holder passthrough 625 and aperture passthrough 635 are sized to provide for a reduction of stray light emanating from lighting source 612.

[0071] Although aperture holder passthrough 625 and aperture passthrough 635 are shown as comprising a circular form, it would be understood that aperture holder passthrough 625 and aperture passthrough 635 may be in a square or rectangular form, or a combination thereof, without altering the scope of the invention. In one aspect or the invention, the circular, the square or the rectangular form of passthroughs 625, 635 may be sized such that the die portion of a semiconductor light emitting diode forming light source 612 may be inserted into at least one of aperture holder passthrough 625 and aperture passthrough 635.

[0072] Further illustrated is a dome lens 640, substantially centered over the passthroughs 625, 635, wherein the lighting source 612 is positioned within or at a focal point of dome lens 640. Dome lens 640 provides for the focusing of the light generated by lighting source 612.

[0073] Further discussion of the invention shall hereinafter make reference to lighting source 675 as being a combination of PCB 611. lighting source 612 and one or more of aperture holder 625. aperture 635 and dome lens 640.Serial No.: TBDFiling Date: TBDFor: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104Attn.: C. A. Giordano, Reg. No.: 41780August2024August 2025

[0074] In this illustrated embodiment, housing 610 further includes an internal screw thread 617, that mates to a corresponding screw thread 1211 (see FIG. 12) on housing 610 to enable housing 610 and lighting element 140 to be rendered as a single unit.

[0075] Although a screw thread is illustrated, it would be recognized that housing 610 and housing 110 may be joined by other means. For example, a bayonet connection, a snap-fit connection, a form fit connection and other similar connections. Further details of the connection of lighting element 140 and housing 110 is made with regard to FIG. 12.

[0076] In accordance with the principles of the invention, lighting source 612 is positioned within a focal length of light lens 235 when lighting element 140 is joined to housing 110. The positioning of light source 612 within the focal lengths of dome lens 640 and light lens 235 provides for a more even distribution of light. See for example, USP 7690806 and 10247384 for further details regarding obtaining a substantially uniform light distribution.

[0077] FIG. 7A illustrates a side view of a first aspect of a second exemplary embodiment of a lighting sources incorporated into light element 140 shown in FIGs. 1-4.

[0078] In this first aspect of lighting element 140, lighting element 140 comprises housing 610 comprising at least one of a plurality of lighting sources 675 arranged about an inner circumference 685 of housing 610.

[0079] As previously discussed, lighting sources 675 in a preferred embodiment includes lighting source 612, aperture 620, aperture holder 630 and dome lens 640, it would be recognized that lighting sources 675 may comprise lighting source 612 and lack one or more of aperture 620, aperture holder 630, and dome lens 640, without altering the scope of in the invention claimed.

[0080] In accordance with this exemplary first aspect of lighting element 140, the illustrated lighting sources 675 are oriented about inner circumference 685 of housing 610 wherein light emitted by lighting sources 675 is directed toward light director 755, which extends from base 615 of housing 610.

[0081] Light director 755 comprises a pyramid or prismatic structure comprises a plurality of reflective surfaces (i.e. , highly polished, mirror, etc.) 742, 744 arranged at an angle to each other such that a peak angle 760 is formed at an apex 759 of reflective surfaces 742, 744. The reflective surfaces 742, 744, receive light emitted by corresponding ones of light sources 675 and redirects the received light towards an area about optical axis 145.Serial No.: TBDFiling Date: TBDFor: Through-the-Lens Lighted Loupe Attn. Doc. No.: DVI104Attn.: C. A. Giordano, Reg. No.: 41780August2024August 2025

[0082] Although two reflective surfaces are illustrated it would be recognized by those skilled in the art that the prismatic structure 755 may comprise three, four or more reflective surfaces joined together at apex 759, as would be know n in the art.

[0083] In accordance with the aspect of the illustrated exemplary embodiment, lighting sources 675 are positioned at different locations along the inner circumference 685 of housing 610, such that light emitted by a first lighting source 675 is projected along light path 772 and contacts light director 755 at a first point 773 and light emitted by a second lighting source 675 is projected along light path 774 and contacts light director 755 at a second point 775. The light from lighting sources the first and second lighting sources 675 is then directed, along axis 722 and 723, respectively, toward (not shown) light director 150 (see FIG. 1, for example). Light sources 675 similarly emit light, which is redirected along axis 720 and 721 light director 755 and directed toward (not shown) light director 150.

[0084] In this illustrated aspect of the invention, apex angle 760 is shown to be greater than ninety (90) degrees as the orientation of light sources 675 is substantially orthogonal to axis 622.
