Description

Technical Field

[0001] This utility model relates to the field of optical experimental equipment technology, specifically to an integrated, highly stable laser beam splitter prism frame. Background Technology

[0002] A laser beam splitter prism, commonly used in optical experiments, is an optical element that uses the principle of refraction to break down light into its constituent spectra. Beam splitters are widely used in physics, optics, chemistry, and other fields, especially in dispersion, spectral analysis, and optical imaging. With the development of technology, beam splitters have not only become indispensable tools in basic optical experiments but also play an important role in modern instrumentation, communication, and astronomical observation.

[0003] A beam splitter prism mount is an indispensable and crucial component of an optical system. It ensures the stability and precise angle adjustment of the beam splitter prism, guaranteeing the efficient operation of optical experiments and instruments. With continuous technological advancements, the design, materials, and manufacturing processes of beam splitter prism mounts have evolved, providing higher precision and more stable optical support for various applications. The primary function of a beam splitter prism mount is to securely fix the beam splitter prism within the optical instrument, ensuring that its position and angle remain unchanged during use. The accuracy of an optical system often depends on the relative position and angle of the beam splitter prism with other optical components. Any minute displacement or angular change in the beam splitter prism can lead to deviations in the dispersion of light, thus affecting experimental results or measurement accuracy. Therefore, beam splitter prism mounts must possess high stability, shock resistance, corrosion resistance, and high precision to ensure their reliability under various environmental conditions.

[0004] Traditional beam splitter prism mounts are mostly fixed structures, consisting of multiple separate components such as pressure feet, base, barrel, support rod, and mount, all secured with multi-stage screws. This requires cumbersome assembly before use, and the beam splitting ratio or optical path direction cannot be dynamically adjusted, making it difficult to meet the requirements of precision experiments. Furthermore, traditional mounts lack a specific rotation angle for beam direction adjustment, causing slight displacements or angular changes that can deviate from the light dispersion effect, thus affecting experimental results or measurement accuracy. With the increasing demands for complexity, stability, precision, integration, and ease of maintenance in optical systems, designing a highly stable, highly precise, user-friendly, and compact integrated precision beam splitter prism mount for adjustable laser beams is of paramount importance. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and proposes an integrated, highly stable laser beam splitter prism frame.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An integrated high-stability laser beam splitter prism frame includes a fixed base, a rotatable support column, and a pressure plate. The fixed base has circumferential graduations on its outer periphery and first internal hexagonal threaded holes evenly distributed on its top. The rotatable support column is inserted above the fixed base, and a graduation pointer is provided on its side wall. The rotatable support column has symmetrically arranged long arc-shaped screw translation slots, which are through slots extending vertically. The screw translation slots mate with the first internal hexagonal threaded holes, and bolts are used to connect the fixed base and the rotatable support column. A prism slot is provided above the rotatable support column, and a prism is placed inside the prism slot. The prism slot is adapted to the bottom surface of the prism, and the top corners of the prism slot are chamfered. The pressure plate is placed above the prism, and the rotatable support column and the pressure plate are detachably connected.

[0008] Furthermore, both the fixed base and the rotatable support column are cylindrical structures.

[0009] Furthermore, the top of the fixed base is provided with an annular plug-in seat, which is coaxially arranged with the fixed base; the rotatable support column is provided with a cylindrical groove that is adapted to the plug-in seat; the rotatable support column and the fixed base are plugged together by the cooperation of the plug-in seat and the cylindrical groove.

[0010] Furthermore, the rotatable support column has a groove structure on both sides of the prism slot, and a screw translation groove is provided on the bottom surface of the groove structure.

[0011] Furthermore, the bottom surface of the fixed base is provided with a second internal hexagonal threaded hole, through which the fixed base is fixed to the optical experimental platform.

[0012] Furthermore, two third hexagonal threaded holes are provided diagonally above the rotatable support column, and fifth hexagonal threaded holes are provided on both sides of the pressure plate. The prism is fixed by bolts connected in the fifth and third hexagonal threaded holes.

[0013] Furthermore, the bottom of the rotatable support column is provided with a fourth internal hexagon threaded hole.

[0014] Furthermore, the pressing tablet has a rectangular structure, and the vertical edges on the pressing tablet are rounded at the outer corners.

[0015] Furthermore, the circumferential scale lines are located near the upper edge of the fixed base; the scale pointer is located at the lower edge of the side wall of the rotatable support column.

[0016] The beneficial effects of this utility model compared to the prior art are as follows:

[0017] 1. The fixed base and rotatable support column of this utility model are integrally formed, which avoids the deformation caused by uneven contact stress in traditional separate frames. At the same time, it also ensures that the material is minimized by changes in external temperature, reducing the overall volume and weight, making the optical system more compact and lightweight, and facilitating installation, transportation and use. Through integrated design and precision machining, the frame can provide stable support and positioning for the prism, effectively reducing the displacement or deformation of optical components caused by external vibration, impact and other factors. Integration can achieve higher assembly precision, ensuring the relative position and angular accuracy between various optical components, reducing the trouble of frequent calibration due to component loosening or position changes.

[0018] 2. This utility model features a fixed base with a circumferential scale, enabling accurate measurement of the rotation angle of the rotatable support column and providing precise angular data for optical experiments. Simultaneously, the circumferential scale lines serve as a reference, facilitating the rapid positioning of the rotatable support column to a specific angle for accurate optical path calibration. Experimenters can rotate optical components to the same angle according to the scale lines, ensuring consistent experimental conditions and improving the repeatability of experimental results. By integrating high-precision angle calibration, the convenience, repeatability, and accuracy of optical path adjustment are significantly improved, making it particularly suitable for complex optical systems requiring frequent adjustments to the rotation angle of the beam splitter prism.

[0019] 3. The rotating support column of this utility model has a screw groove at the center below, which allows the component to rotate freely and can be disassembled individually or recombined with other components. This enhances the reconfigurability, facilitates maintenance and replacement, and improves the functionality of the eyeglass frame.

[0020] 4. The prism frame described in this utility model is a small cylinder. It is small in size and regular in shape, and can be closely arranged in an optical system, which effectively saves time. It is especially suitable for small optical equipment with compact space. The small cylindrical frame has a simple processing technology, is suitable for mass production and has low cost and short processing cycle. Furthermore, it can be used in different experimental environments with different requirements by selecting different materials.

[0021] 5. The prism holder described in this utility model does not require pressure feet for fixation, eliminating the space occupied by pressure feet and effectively increasing the usable area of ​​the optical platform, which is especially beneficial for compact systems. At the same time, it avoids the discrete tightening steps of pressure foot screws, reduces the impact of mechanical stress on optical components, supports real-time operation of optical path fine adjustment, improves adjustment accuracy, and simplifies the installation and adjustment process.

[0022] 6. The prism holder of this utility model features rounded corners at the four corners of the prism groove. Right-angled grooves are prone to stress concentration under external force, leading to cracks or even damage to the prism. The rounded corners disperse stress, making the prism easier to place and improving the strength and durability of both the holder and the prism. The rounded corners also eliminate the problem of dust accumulation at right angles, making cleaning easier and maintaining good optical performance. Attached Figure Description

Detailed Implementation

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0032] like Figures 1 to 5As shown, this embodiment proposes an integrated high-stability laser beam splitter prism frame, which includes a fixed base 1, a rotatable support column 2, and a pressure plate 4;

[0033] The fixed base 1 has a cylindrical structure with a hollow center; the fixed base 1 has a circumferential scale line 14 on its outer periphery, which is close to the upper edge of the fixed base 1; the circumferential scale line 14 is formed by laser etching, with a minimum division value of 2°.

[0034] The top of the fixed base 1 is provided with an annular plug-in seat 16 and four first internal hexagonal threaded holes 13 evenly distributed thereon; the plug-in seat 16 is coaxially arranged with the fixed base 1, and is used to fit into the rotatable support column 2; the first internal hexagonal threaded holes 13 are arranged around the plug-in seat 16, and are used to fix the rotatable support column 2; the bottom surface of the fixed base 1 is provided with a second internal hexagonal threaded hole 15, and is used to fix the fixed base 1 on the optical experimental platform.

[0035] The rotatable support column 2 is also cylindrical in shape. The rotatable support column 2 is located above the fixed base 1. The rotatable support column 2 is provided with a cylindrical groove that is compatible with the plug-in seat 16. The rotatable support column 2 and the fixed base 1 can be plugged together by the cooperation of the plug-in seat 16 and the cylindrical groove.

[0036] The rotatable support column 2 has two diagonally opposite third hexagonal threaded holes 7 on its upper part. The rotatable support column 2 uses the third hexagonal threaded holes 7 to cooperate with the pressure plate 4 to fix the prism 3. The rotatable support column 2 has a prism groove 11 on its upper part. The prism groove 11 is adapted to the bottom surface of the prism 3. The four corners of the prism groove 11 are all provided with chamfers 8. The prism groove 11 makes it easier to align and insert the prism 3, reducing assembly difficulties caused by the edges. At the same time, the sharp edges of the prism 3 are prone to stress concentration, which can lead to cracks or breakage. The chamfers 8 can disperse the stress and extend the life of the prism 3.

[0037] The rotatable support column 2 has groove structures on both sides of the prism groove 11. The bottom surface of each groove structure has a long arc-shaped screw translation groove 10, which is a through groove running vertically. The screw translation groove 10, in conjunction with the first internal hexagonal threaded hole 13, is used to fix the fixed base 1 and the rotatable support column 2. Because the screw translation groove 10 is a long arc-shaped structure, even after the rotatable support column 2 rotates relative to the fixed base 1 by a certain angle, it can still be fixed to the fixed base 1 through the engagement of the screw translation groove 10 and the first internal hexagonal threaded hole 13.

[0038] The rotatable support column 2 has a fourth internal hexagonal threaded hole 12 at its bottom. When it is necessary to remove the rotatable support column 2 from the fixed base 1 and use it independently, it can be directly fixed to the optical experimental platform through the fourth internal hexagonal threaded hole 12 for standalone use. Experimenters can freely combine modules according to experimental needs to quickly build specific optical paths, achieve iterative upgrades of system functions, avoid the obsolescence of the entire equipment, and enhance the functional versatility of the frame.

[0039] The lower edge of the side wall of the rotatable support column 2 is equipped with a scale pointer 9, which works in conjunction with the circumferential scale line 14 on the upper edge of the fixed base 1 for precise angle adjustment. Using the scale pointer 9 and the circumferential scale line 14, experimenters can quickly restore the preset angle, reducing repetitive calibration time and improving experimental efficiency.

[0040] The pressure plate 4 has a rectangular structure, and fifth internal hexagonal threaded holes 5 are provided on both sides of the pressure plate 4. The prism 3 is fixed by bolts connected in the fifth internal hexagonal threaded holes 5 and the third internal hexagonal threaded holes 7.

[0041] The vertical edges on the pressure plate 4 are rounded to the outside to avoid contact between the frame and the optical components, and to prevent scratches to the experimental personnel.

[0042] The entire prism frame is a cylindrical element, small in size, allowing for dense arrangement within a limited space and achieving a high degree of integration of complex optical paths. The cylindrical structure is more robust and less prone to deformation under pressure or vibration, which is crucial for optical systems requiring high stability. At the same time, it is lightweight, occupies little space, and is easy to use.

[0043] This embodiment proposes a method for using an integrated, highly stable laser beam splitter prism frame:

[0044] 1. First, check that all parts are intact;

[0045] 2. After the test is passed, fix the fixed base 1 to the optical experimental platform through the second internal hexagonal threaded hole 15; then use bolts to connect the screw translation slot 10 to the corresponding first internal hexagonal threaded hole 13, thereby fixing the fixed base 1 and the rotatable support column 2. Then, put the prism 3 into the prism slot 11, and then place the pressure plate 4 on top of the prism 3. Finally, use bolts to connect the third internal hexagonal threaded hole 7 and the fifth internal hexagonal threaded hole 5 to fix the prism 3.

[0046] 3. Inject a laser beam into this device and verify the stability of the beam-splitting prism frame by observing the laser beam splitting.

[0047] 4. Loosen the bolts between the adjustable screw sliding groove 10 and the first internal hexagon threaded hole 13, rotate the rotatable support column 2 by a certain angle, observe the deviation of the emitted beam, and then check the beam splitting accuracy of the frame.

[0048] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
