Description

Technical Field

[0001] This invention relates to the field of spectroscopic instruments and equipment, and in particular to a multi-angle planar spectroscopic analyzer. Background Technology

[0002] Existing testing instruments for planar optical lenses mostly use grating scanning to measure transmittance when testing the optical performance of lenses. This method can only measure the refraction or reflection of light at a specific angle of the lens at a time. If a measurement at another angle is needed, the lens under test must be reloaded and the position of the reflecting lens adjusted. Adjusting the relative angle between the lens under test and the reflecting lens requires manual adjustment, resulting in low testing efficiency and considerable difficulty. Furthermore, existing testing instruments for planar optical lenses can generally detect light wavelengths in the range of 380~1100nm, a relatively narrow range, thus failing to provide accurate results regarding the optical lens's performance.

[0003] As shown in Chinese invention patent publication number CN103968942A, a fully automatic planar spectrum analyzer is disclosed, including an outer cover, a light source, an optical path connected to the front end of the light source, a two-axis controller, a stage connected to the two-axis controller, a detection device connected to the two-axis controller, and a data processing device connected to the detection device. The two-axis controller is connected to the data processing device. The detection device includes a reflector and a detector. The detector includes a visible light detector and an invisible light detector connected in parallel.

[0004] This fully automated planar spectrometer features the ability to conveniently and quickly detect the refraction and reflection properties of light at any angle using optical lenses, boasts high detection efficiency, and can detect a wide wavelength range, thus solving the aforementioned technical problems. However, in practical use, it also has the following issues: The position of the light source that generates parallel light paths is fixed, the light path is singular and cannot be adjusted, resulting in poor applicability. Summary of the Invention

[0005] The purpose of this invention is to provide a versatile multi-angle planar spectrometer that can at least solve one of the above-mentioned problems.

[0006] According to one aspect of the present invention, a multi-angle planar spectrometer is provided, comprising a frame, a light source, a parallel optical path, a multi-angle adjustment device, a detection device, and a control device; The parallel optical path is installed on a multi-angle adjustment device and is matched with the light source; The detection device is mounted on the frame and is compatible with the parallel optical path; The multi-angle adjustment device is mounted on the frame and is used to achieve multi-angle adjustment of the parallel optical path; The control device is electrically connected to the light source, multi-angle adjustment device, and detection device; The multi-angle adjustment device includes a lifting mechanism, a translation mechanism, and a tilting mechanism. The lifting mechanism is mounted on the frame, the translation mechanism is mounted on the lifting mechanism, the tilting mechanism is mounted on the translation mechanism, and the parallel optical path is mounted on the tilting mechanism. The lifting mechanism includes a first mounting block, a first control component, and a scissor lift frame. The first mounting block is mounted on the frame, the scissor lift frame is mounted on the first mounting block, the first control component cooperates with the scissor lift frame, and the translation mechanism is mounted on the scissor lift frame. The translation mechanism includes a second mounting block, a second control component, and a first guide assembly. The second mounting block is mounted on the scissor lift frame, the first guide assembly is mounted on the second mounting block, and the second control component is mounted on the second mounting block and cooperates with the first guide assembly. The first guide assembly includes a first slider and a first linear guide rail. The first linear guide rail is mounted on the second mounting block, and the first slider slides with the first linear guide rail through a first groove at the bottom. The tilting mechanism is mounted on the first slider, and the second control component cooperates with the first slider. The tilting mechanism includes a movable platform, a fixed platform, a third control component, and a first limiting component. The fixed platform is mounted on the first slider, the movable platform is mounted on the fixed platform and can move relative to the fixed platform, the third control component is mounted on the fixed platform and cooperates with the movable platform, the first limiting component is mounted on the movable platform, and the parallel optical path is mounted on the first limiting component. The upper end of the fixed platform is provided with an arc-shaped groove, and the lower end of the movable platform is provided with an arc-shaped protrusion that cooperates with the arc-shaped groove. The second guide assembly includes a second slide groove and a second linear guide rail. The second linear guide rail is installed on the upper end of the fixed platform, and the second slide groove is opened at the lower end of the movable platform and slides in cooperation with the second linear guide rail.

[0007] Therefore, the present invention provides a novel multi-angle plane spectrometer, which adds a multi-angle adjustment device to the traditional structure, enabling adjustment of lifting, translation and angle in three axes, thereby achieving adjustment of multiple angles of parallel paths, facilitating rapid multi-directional and multi-point detection, and having strong applicability.

[0008] In some embodiments, the first slide is a U-shaped groove, and the second slide is a dovetail groove. Thus, the translation mechanism uses the U-shaped groove for guidance and achieves translation through the second control element, while the tilting mechanism uses the dovetail groove for guidance and achieves tilting adjustment through the third control element.

[0009] In some embodiments, the detection device includes a first rotating stage mechanism, a second rotating stage mechanism, a clamping mechanism, a reflector, a receiver, and a detector. The clamping mechanism is mounted on the first rotating stage mechanism and is used to clamp the lens to be tested. The first rotating stage mechanism is mounted on the second rotating stage mechanism, and the reflector, receiver, and detector are all mounted on the second rotating stage mechanism. Therefore, the operating principle of the detection device is as follows: light emitted from the light source passes through a parallel light path to generate parallel light. This parallel light acts on the lens to be tested, held by the clamping mechanism. Through the action of the first and second rotating stage mechanisms, the reflector, receiver, and detector can be rotated at an appropriate angle, so that the parallel light acts horizontally on the lens to be tested. The light transmitted through the lens to be tested acts horizontally on the reflector. The light acting on the reflector passes through the receiver, and the light energy is transmitted via optical fiber to the detector. The control device then calculates the transmittance curve of the lens to be tested from the energy transmitted to the detector and displays the detection result, thereby measuring the transmittance of the lens to be tested. The detection time is within 0.5 seconds, indicating high speed and efficiency.

[0010] In some implementations, the detector includes a visible light detector and an invisible light detector connected in parallel.

[0011] In some embodiments, the first rotary table mechanism includes a first rotary table and a first driving member, and the second rotary table mechanism includes a second rotary table and a second driving member. The first and second driving members are electrically connected to a control device. The second rotary table is mounted on a frame, and the driving end of the second driving member is connected to the second rotary table. The first rotary table is mounted above the second rotary table, and the driving end of the first driving member is connected to the first rotary table. This allows for automatic swing adjustment of the positions of the first and second rotary tables.

[0012] In some embodiments, the detection device further includes a first mounting bracket mounted on a second rotating stage, on which the reflector, receiver, and detector are all mounted. This facilitates the installation of the reflector, receiver, and detector.

[0013] In some embodiments, the first rotary table mechanism further includes a first detection component electrically connected to the control device. The first detection component includes a first sensor and a first sensing element. The first sensing element is mounted on the first rotary table, and the first sensor is mounted on the frame and cooperates with the first sensing element.

The second detection component includes a second sensor and a second sensing element. The second sensing element is mounted on the second rotary table, and the second sensor is mounted on the frame and cooperates with the second sensing element. This facilitates precise automatic rotation of the first and second rotary tables.

[0014] In some embodiments, the clamping mechanism includes a second mounting bracket, a second slider, a fourth control component, and a third linear guide rail. The second mounting bracket is mounted on a first rotary table, the third linear guide rail and the fourth control component are mounted on the second mounting bracket, the second slider slides in cooperation with the third linear guide rail and forms a limiting space between the slider and the second mounting bracket to cooperate with the lens under test, and the fourth control component is mounted on the second mounting bracket and cooperates with the second slider. This facilitates quick replacement of the lens under test.

[0015] In some embodiments, the clamping mechanism further includes a guide post mounted on a second mounting bracket, and a second slider fitted onto the guide post.

[0016] In some embodiments, the detection device further includes a second limiting member, which is mounted on the frame and engages with the second rotary table for limiting.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Figures 1-9 A multi-angle planar spectrometer according to an embodiment of the present invention is schematically shown.

[0022] like Figures 1-9 As shown, the multi-angle planar spectrometer includes a frame 1, a light source 2, a parallel optical path 3, a multi-angle adjustment device 4, a detection device 5, and a control device 6; Parallel optical path 3 is installed on multi-angle adjustment device 4 and cooperates with light source 2; The detection device 5 is mounted on the frame 1 and is compatible with the parallel optical path 3; The multi-angle adjustment device 4 is installed on the frame 1 and is used to realize multi-angle adjustment of the parallel optical path 3; The control device 6 is electrically connected to the light source 2, the multi-angle adjustment device 4, and the detection device 5.

[0023] like Figure 1-6 As shown, the multi-angle adjustment device 4 includes a lifting mechanism 41, a translation mechanism 42, and a tilting mechanism 43. The lifting mechanism 41 is mounted on the frame 1, the translation mechanism 42 is mounted on the lifting mechanism 41, the tilting mechanism 43 is mounted on the translation mechanism 42, and the parallel optical path 3 is mounted on the tilting mechanism 43. Thus, three-axis adjustment of lifting, translation, and angle can be realized.

[0024] The lifting mechanism 41 includes a first mounting block 411, a first control element 412, and a scissor lift frame 413. The first mounting block 411 is mounted on the frame 1, the scissor lift frame 413 is mounted on the first mounting block 411, the first control element 412 cooperates with the scissor lift frame 413, and a translation mechanism 42 is mounted on the scissor lift frame 413. Thus, the lifting mechanism 41 uses the cooperation of the scissor lift frame 413 and the first control element 412 to achieve height adjustment of the parallel optical path 3.

[0025] The first control component 412 in this embodiment can be a manual control knob, a hand crank, a cylinder, or a hydraulic cylinder, etc., for folding or unfolding the scissor lift 413.

[0026] The translation mechanism includes a second mounting block 421, a second control component 422, and a first guide assembly 423. The second mounting block 421 is mounted on the scissor lift frame 413, the first guide assembly 423 is mounted on the second mounting block 421, and the second control component 422 is mounted on the second mounting block 421 and cooperates with the first guide assembly 423. The first guide assembly 423 includes a first slider 423a and a first linear guide rail 423b. The first linear guide rail 423b is mounted on the second mounting block 421. The first slider 423a slides with the first linear guide rail 423b through a first groove 423c at its bottom. A tilting mechanism 43 is mounted on the first slider 423a, and the second control component 422 cooperates with the first slider 423a. Thus, the combined cooperation of the second control component 422 and the first guide assembly 423 achieves the translation of the parallel light path 3.

[0027] The second control element 422 in this embodiment can be a control knob for causing the first slider 423a to slide relative to the first linear guide rail 423b, such as a differential head.

[0028] The tilting mechanism 43 includes a movable platform 431, a fixed platform 432, a third control component 434, and a first limiting component 435. The fixed platform 432 is mounted on the first slider 423a, the movable platform 431 is mounted on the fixed platform 432 and can move relative to the fixed platform 432, the third control component 434 is mounted on the fixed platform 432 and cooperates with the movable platform 431, the first limiting component 435 is mounted on the movable platform 431, the parallel optical path 3 is mounted on the first limiting component 435, the upper end of the fixed platform 432 is provided with an arc-shaped groove 432a, and the lower end of the movable platform 431 is provided with an arc-shaped protrusion 431a that cooperates with the arc-shaped groove 432a. The second guide component 433 includes a second slide groove 433a and a second linear guide rail 433b. The second linear guide rail 433b is installed on the upper end of the fixed platform 432. The second slide groove 433a is opened at the lower end of the movable platform 431 and slides with the second linear guide rail 433b. The second slide groove 433a is a dovetail groove.

[0029] Therefore, the tilting mechanism 43 uses a dovetail groove for guidance, and tilting adjustment is achieved by rotating the third control component 434.

[0030] In this embodiment, the third control element 434 can be a control knob for causing the movable stage 431 to slide relative to the second linear guide rail 433b, such as a differential head.

[0031] like Figure 1-3 as well as Figure 7-9As shown, the detection device 5 includes a first rotary table mechanism 51, a second rotary table mechanism 52, a clamping mechanism 53, a reflector 54, a receiver 55, and a detector 56. The clamping mechanism 53 is mounted on the first rotary table mechanism 51 and is used to clamp the lens to be tested. The first rotary table mechanism 51 is mounted on the second rotary table mechanism 52. The reflector 54, receiver 55, and detector 56 are all mounted on the second rotary table mechanism 52. The first rotary table mechanism 51 is used to drive the clamping mechanism 53 to swing, and the second rotary table mechanism 52 is used to drive the first rotary table mechanism 51 and the clamping mechanism 53, reflector 54, receiver 55, and detector 56 mounted on the first rotary table mechanism 51 to swing together. Therefore, the operating principle of the detection device 5 is as follows: the light emitted by the light source 2 passes through the parallel light path 3 to generate parallel light, which acts on the lens to be tested held by the clamping mechanism 53. Through the action of the second rotating stage mechanism 52, the reflector 54, receiver 55 and detector 56 can be rotated at an appropriate angle, so that the parallel light acts horizontally on the lens to be tested, and the light passing through the lens to be tested acts horizontally on the reflector 54. The light acting on the reflector 54 passes through the receiver 55 and transmits the light energy through the optical fiber to the detector 56. The control device 6 then calculates the transmittance energy curve of the lens to be tested from the energy transmitted to the detector 56 and displays the detection result, thereby measuring the transmittance of the lens to be tested. The detection time is within 0.5s, and the detection speed is fast and the efficiency is high.

[0032] Detector 56 includes a visible light detector 561 and an invisible light detector 562561 connected in parallel.

[0033] The first rotary table mechanism 51 includes a first rotary table 511 and a first driving member 512. The second rotary table mechanism 52 includes a second rotary table 521 and a second driving member 522. The first driving member 512 and the second driving member 522 are electrically connected to the control device 6. The second rotary table 521 is mounted on the frame 1. The driving end of the second driving member 522 is connected to the second rotary table 521. The first rotary table 511 is mounted above the second rotary table 521. The driving end of the first driving member 512 is connected to the first rotary table 511. Thus, the automatic swing adjustment of the positions of the first rotary table 511 and the second rotary table 521 can be achieved.

[0034] The detection device 5 in this embodiment also includes a first mounting frame 57, which is mounted on the second rotating stage 521. The reflector 54, receiver 55 and detector 56 are mounted on the first mounting frame 57.

[0035] The first rotary table mechanism 51 further includes a first detection component 513 electrically connected to the control device 6. The first detection component 513 includes a first sensor 513a and a first sensing element 513b. The first sensing element 513b is mounted on the first rotary table 511, and the first sensor 513a is mounted on the frame 1 and cooperates with the first sensing element 513b. The second rotary table mechanism 52 further includes a second detection component 523 electrically connected to the control device 6. The second detection component 523 includes a second sensor 523a and a second sensing element 523b. The second sensing element 523b is mounted on the second rotary table 521, and the second sensor 523a is mounted on the frame 1 and cooperates with the second sensing element 523b. This facilitates precise automatic rotation of the first rotary table 511 and the second rotary table 521.

[0036] The control device 6 in this embodiment is a circuit control system, and can also be used in conjunction with a computer, host, etc. to achieve automated control.

[0037] like Figure 9 As shown, the clamping mechanism 53 includes a second mounting bracket 531, a second slider 532, a fourth control component 533, and a third linear guide rail 534. The second mounting bracket 531 is mounted on the first rotary table 511. The third linear guide rail 534 and the fourth control component 533 are mounted on the second mounting bracket 531. The second slider 532 slides in cooperation with the third linear guide rail 534 and forms a limiting space 530 between itself and the second mounting bracket 531, which is suitable for the lens under test. The fourth control component 533 is mounted on the second mounting bracket 531 and cooperates with the second slider 532. This allows for quick and easy replacement of the lens under test.

[0038] In this embodiment, the fourth control component 533 can be a lead screw, which, together with the nut set at the bottom of the second slider 532, can realize the translational movement of the second slider 532, thereby clamping or releasing the lens to be tested.

[0039] The clamping mechanism 53 also includes a guide post 535, which is mounted on the second mounting bracket 531, and the second slider 532 is fitted onto the guide post 535.

[0040] like Figure 1-2 As shown, the detection device 5 of this embodiment also includes a second limiting member 58, which is mounted on the frame 1 and engages with the second rotary table 521 for limiting. This effectively prevents the second rotary table 521 from exceeding its travel range.

[0041] In this embodiment, the incident light source 2 is preferably a deuterium-halogen combination light source.

[0042] Tests have shown that the measurement wavelength range of this embodiment is 260-2500nm.

[0043] This invention provides a novel multi-angle plane spectrometer, which adds a multi-angle adjustment device 4 to the traditional structure, enabling adjustment of multiple angles of the parallel path, facilitating rapid multi-directional and multi-point detection, and has strong applicability.

[0044] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
