The integration accuracy of the crystal transmittance detection device affects the consistency of crystal transmittance, thus affecting the quality of optical signal acquisition. The crystal transmittance detection device detects crystals in different channels of the mount, generally using a fixed detector and a moving light source and mount.

[0003] Existing detection methods introduce human error when moving the light source and mirror mount, which affects the consistency of crystal transmittance in different channels of the mirror mount. This requires repeated attempts, making adjustment difficult and cumbersome, and it is difficult to meet the accuracy requirements in actual adjustment.

[0004] Therefore, it is necessary to design a crystal transmittance detection device to solve the above problems. Summary of the Invention

[0005] In view of this, in order to overcome the shortcomings of the prior art, the present invention provides a crystal transmittance detection device, which effectively solves the problems of human operation error, large adjustment difficulty, cumbersome steps and insufficient accuracy caused by the need to move the light source and lens mount in the existing crystal transmittance detection device.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the embodiments of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to the present invention, a crystal transmittance detection device is provided, such as... Figures 1 to 6 As shown, the crystal transmittance detection device is used to detect the transmittance of each crystal (optical element) in the optical lens mount 5. The crystal transmittance detection device includes a light source mechanism 1, a lens mount fixing mechanism 2, and a detection mechanism 3.

[0026] In the following description, reference will be made to Figures 1 to 6 The detailed structure of the light source mechanism 1, the mirror mount fixing mechanism 2, and the detection mechanism 3 of the crystal transmittance detection device is described in detail.

[0027] like Figures 1 to 3 As shown, in this embodiment, the light source mechanism 1 and the detection mechanism 3 are respectively disposed at both ends of the mirror mount fixing mechanism 2 in the first direction S1; the first direction S1 can be understood as... Figure 1 The light source mechanism 1 can emit detection light in the left-right direction or in the length direction of the base plate 4 described below. The detection mechanism 3 can receive the light after it passes through the lens mount fixing mechanism 2 and perform detection. The light source mechanism 1 and the detection mechanism 3 can use existing mechanisms in existing crystal transmittance detection devices. Those skilled in the art can select different specifications of mechanisms according to the detection needs, which will not be described in detail here.

[0028] Specifically, the lens mount fixing mechanism 2 may include a mounting base 201 and a clamping assembly. The mounting base 201 has fiber optic connection holes 214 on its end face facing the light source mechanism 1. The number of fiber optic connection holes 214 can be multiple, and the specific number can be selected based on the number of fibers in the first fiber 102 and the second fiber 103 described below. The size of the fiber optic connection holes 214 can limit the length of the first fiber 102 and the second fiber 103 inserted into the mounting base 201, thereby controlling the distance between the first fiber 102 and the second fiber 103 and the crystal in the optical lens mount 5.

[0029] like Figure 4As shown, the mounting base 201 has a first mounting groove 202 on the end face facing the detection mechanism 3. The optical lens mount 5 is disposed in the first mounting groove 202. The first mounting groove 202 can be formed into a rectangular groove, and the size of the first mounting groove 202 can correspond to the size of the optical lens mount 5, so that the optical lens mount 5 can be placed in the first mounting groove 202 and correspond to the fiber optic connection hole 214 to meet the requirements of transmittance detection.

[0030] Furthermore, the clamping assembly passes through the top surface of the mounting base 201 and abuts against the optical lens mount 5. The clamping assembly can limit the displacement of the optical lens mount 5 and fix the optical lens mount 5 by abutting and pressing. When it is necessary to replace different test objects, the clamping assembly can be loosened and the optical lens mount 5 can be replaced directly.

[0031] Furthermore, the mounting base 201 has a second mounting groove 203 on its side in the second direction S2, where the second direction S2 can be understood as the width direction of the base plate 4 described below. The second mounting groove 203 is disposed between the first mounting groove 202 and the optical fiber connection hole 214 along the second direction S2. The aperture 208 described below can be inserted into the second mounting groove 203 to detect the transmittance of the crystal in different channels. Similarly, when it is necessary to detect the light intensity signal of other optical channels, the aperture 208 can be pulled out from the second mounting groove 203 and a different aperture 208 can be directly replaced.

[0032] This crystal transmittance detection device, through the cooperation of the light source mechanism 1, the mirror base fixing mechanism 2, and the detection mechanism 3, ensures that these three components remain relatively fixed during the crystal transmittance detection process. This avoids operational errors caused by human movement and guarantees the consistency of crystal transmittance in different channels of the optical mirror base 5. The optical mirror base 5 is fixed and detected by using the first mounting slot 202 in conjunction with the clamping assembly. Different detection components can be replaced using the second mounting slot 203 to detect the light intensity signal of other light-transmitting channels. This makes the overall operation process simple and convenient, eliminating the need for repeated attempts, reducing adjustment difficulty, and improving adjustment and detection accuracy during the detection process. It can also detect the crystal transmittance in a single channel.

[0033] Preferably, such as Figures 1 to 4As shown, in this embodiment, the mounting base 201 has a clamping channel 204 that extends from the top surface of the mounting base 201 to the first mounting groove 202. A clamping assembly is disposed within the clamping channel 204. Specifically, the clamping assembly may include a spring rod 205 and a clamping support 206. The clamping support 206 includes a clamping plate portion and a sleeve portion. The clamping plate portion is threadedly connected to the top surface of the mounting base 201, and the sleeve portion is disposed within the clamping channel 204. The clamping plate portion and the sleeve portion can be integrally formed components. The spring rod 205 includes a rod body and a spring element sleeved on the rod body. The rod body and the spring element pass through the clamping support 206, and the spring element enables reset and clamping. The two ends of the spring rod 205 are a tightening end and a pulling end, respectively. The tightening end abuts against the optical lens mount 5, and the pulling end is located outside the clamping plate portion, facilitating the user to pull the spring rod 205. When the user pulls the spring lever 205, the spring lever 205 moves along the sleeve towards the top of the mounting base 201 and compresses the spring. At this time, the optical lens base 5 can be placed in the first mounting groove 202. Afterwards, the user releases the spring lever 205, and the spring lever 205 is reset by the elastic force. The top end abuts against and presses the optical lens base 5.

[0034] Preferably, such as Figure 4 As shown, in this embodiment, the second direction S2 is perpendicular to the first direction S1. The lens mount fixing mechanism 2 may further include a docking replacement component 207, which is snapped into the second mounting groove 203. An aperture 208 and a plug-in block 209 are respectively provided at both ends of the docking replacement component 207. The user can insert and remove the docking replacement component 207 within the second mounting groove 203 using the plug-in block 209 to replace different apertures 208.

[0035] Preferably, such as Figures 1 to 4 As shown in the embodiment, the mounting base 201 has two sets of parallel fiber optic connection holes 214 on its end face facing the light source mechanism 1, and two first mounting slots 202 corresponding to the two sets of fiber optic connection holes 214 on its end face facing the detection mechanism 3. A second mounting slot 203 is provided between each of the corresponding fiber optic connection holes 214 and the first mounting slots 202. The mounting base 201 can simultaneously perform two sets of crystal transmittance detections, i.e., simultaneously install two optical lens mounts 5. To avoid interference, it should be emphasized that the installation and insertion / removal directions of the two second mounting slots 203 and the two docking replacement parts 207 are opposite to each other; that is, the two second mounting slots 203 are respectively located on two opposite sides of the mounting base 201 in the second direction S2.

[0036] Preferably, such as Figures 4 to 6As shown, in this embodiment, the mounting base 201 has a recessed portion 210 on its end face facing the detection mechanism 3. The recessed portion 210 is recessed in a direction away from the detection mechanism 3. A first mounting groove 202 is formed in the recessed portion 210, which is used to mount the circuit board 6. This crystal transmittance detection device can also be used to detect the circuit board 6, which can be placed on the recessed portion 210 and detected by the detection mechanism 3.

[0037] Preferably, such as Figure 6 As shown, in the embodiment, the recessed portion 210 is provided with connection positions 211 on both sides. The connection positions 211 may include multiple threaded holes. The mirror base fixing mechanism 2 may also include a rotating fixing component, which is provided in the connection position 211 by means of a threaded connection.

[0038] Preferably, such as Figure 6 As shown, in this embodiment, the rotating fixing assembly may include a connecting plate 212 and a rotating rod 213. The connecting plate 212 is threadedly connected to the connecting position 211. One end of the rotating rod 213 is rotatably connected to the connecting plate 212 via a rotating shaft. A tightening bolt is provided at the end of the rotating rod 213. When the plate 6 is located in the recess 210, the rotating rod 213 is rotated, and the tightening bolt is tightened, causing the tightening bolt to abut against the plate 6. There can be two rotating fixing assemblies, which are arranged facing each other on both sides of the recess 210. Thus, the plate 6 can be abutted and fixed by the two rotating fixing assemblies.

[0039] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the light source mechanism 1 may include a laser 101 and a split optical fiber. The split optical fiber may include a first split optical fiber 102 and a second split optical fiber 103, so as to correspond to the two sets of optical fiber connection holes 214 and the two first mounting slots 202, and realize the simultaneous detection of the two optical lens mounts 5. The two ends of the split optical fiber are connected to the laser 101 and the optical fiber connection hole 214, respectively.

[0040] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the crystal transmittance detection device may further include a base plate 4, and the light source mechanism 1, the mirror mount fixing mechanism 2, and the detection mechanism 3 are all provided with a base plate 4.

[0041] Preferably, such as Figures 1 to 3As shown, in this embodiment, the base plate 4 has a groove slide 401, and the detection mechanism 3 is arbitrarily positioned in the groove slide 401. The adjustment method can be, for example, a sliding connection or a threaded connection. In the case of a sliding connection, the groove slide 401 is provided with a slide rail, and the bottom of the detection fixing seat 301 of the detection mechanism 3 is provided with a slider. The position adjustment of the detection mechanism 3 in the second direction S2 is achieved by the sliding connection between the slider and the slide rail. In the case of a threaded connection, the groove slide 401 has multiple threaded holes, and the bottom sides of the detection fixing seat 301 are provided with outwardly protruding connecting blocks. The connecting blocks can be threadedly connected to the threaded holes at different positions.

[0042] The detection process of this crystal transmittance detection device is as follows: For the inspection of optical mount 5: The first step is to integrate the split fiber into the fiber optic interface of the mounting base 201 and fix the split fiber using the hole-shaft mating. The second step is to lift the spring lever 205 and place the optical lens mount 5 in the first mounting groove 202 of the mounting base 201. The optical lens mount 5 contains crystals with different channels. Then, loosen the spring lever 205 to fix the optical lens mount 5. The third step is to insert the docking replacement part 207 into the second mounting slot 203 of the mounting base 201. The aperture 208 can block four light transmission channels, leaving only one light transmission channel. The fourth step is to adjust the detector of the detection mechanism 3 to the calibrated position, turn on the laser 101, adjust it to the specified light intensity signal, and read the detector reading. Fifth, replace different apertures 208, and sequentially detect the light intensity signals of the other four light-transmitting channels, and read the detector readings; Step 6: Lift the spring lever 205, remove the optical lens mount 5, place other optical lens mounts 5, and repeat the above steps for testing.

[0043] Testing of board 6: The first step is to connect the split fiber to the fiber optic interface of the mounting base 201 and fix the split fiber using the hole-shaft fit. The second step is to lift the spring lever 205, place the optical lens mount 5 on the plate 6 in the first mounting slot 202 of the mounting base 201, and loosen the spring lever 205 to fix the optical lens mount 5. Third step, rotate the rotating rod 213 and use the tightening bolt to tighten the plate 6 and fix the plate 6.

[0044] The fourth step is to connect the ribbon cable of board 6 to the chassis and perform dark current detection. Fifth step, disconnect the ribbon cable, loosen the tightening bolt, rotate the rotating rod 213, lift the spring pull rod 205, remove the board 6, place other boards 6, and repeat the above steps to perform the test.

[0045] This crystal transmittance detection device, through the cooperation of a light source mechanism, a mirror mount fixing mechanism, and a detection mechanism, ensures that these three components remain relatively fixed during the crystal transmittance detection process. This avoids operational errors caused by human movement and guarantees the consistency of crystal transmittance in different channels of the optical mirror mount. The optical mirror mount is fixed by clamping components using a first mounting slot, thereby achieving fixation and detection of the optical mirror mount. Different detection components can be replaced using a second mounting slot to detect the light intensity signal of other light-transmitting channels. This makes the overall operation process simple and convenient, eliminating the need for repeated attempts, reducing adjustment difficulty, and improving adjustment and detection accuracy during the detection process. It can also detect the crystal transmittance in a single channel.
