Description

Technical Field

[0001] This utility model relates to the field of antireflection film detection, and in particular to a device for detecting the penetration of antireflection film in a specific wavelength band. Background Technology

[0002] With the rapid development of optical technology, antireflective coatings, as a key optical component, are widely used in various optical instruments and equipment, such as camera lenses, telescopes, and microscopes. The main function of antireflective coatings is to reduce reflections on the surface of optical components and increase light transmittance, thereby enhancing the imaging quality and energy transmission efficiency of optical systems. Different types of antireflective coatings have different optical properties for specific wavelengths of light.

[0003] Existing methods for specific wavelength transmission testing of antireflective coatings typically involve mounting the coating on a support and then irradiating it with a light source. However, current equipment can only install a single antireflective coating at a time for testing. After testing a single coating, it must be removed and a new coating installed for testing. This requires frequent replacement of the coating, making the operation cumbersome, time-consuming, and potentially affecting testing efficiency and accuracy. It also makes it difficult to comprehensively evaluate the performance of the antireflective coating.

[0004] Therefore, there is a need to design an antireflection membrane specific band transmission detection device that can rotate four different or the same type of antireflection membranes under a specific wavelength band for transmission detection. This device is simple to operate, does not require frequent replacement of antireflection membranes, facilitates comprehensive evaluation of antireflection membrane performance, and improves detection efficiency and accuracy. Utility Model Content

[0005] To overcome the shortcomings of current equipment that can only install a single antireflection membrane for testing at a time, requiring frequent membrane replacements after each test, which is cumbersome, time-consuming, and can affect testing efficiency and accuracy, and makes it difficult to comprehensively evaluate the performance of the antireflection membrane, this invention provides an antireflection membrane specific band transmission detection device that can rotate four different or the same type of antireflection membrane at a specific wavelength for transmission detection. This device is simple to operate, eliminates the need for frequent membrane replacements, facilitates comprehensive evaluation of antireflection membrane performance, and improves testing efficiency and accuracy.

[0006] The technical implementation scheme of this utility model is as follows: a specific band penetration detection device for antireflective coating, including a detection box, a sealed door, a running light, a display screen, a detection component, and an installation component. The sealed door is rotatably connected to the lower front part of the detection box, the running light is connected to the upper left side of the detection box, and the display screen is connected to the right front part of the detection box. The detection box is equipped with a detection component for detecting the permeability of the antireflective coating, and the bottom of the detection box is equipped with an installation component for installing the antireflective coating.

[0007] In a preferred embodiment of this utility model, a limiting rod is provided on the upper front side of the detection box via a damped rotation.

[0008] In a preferred embodiment of this utility model, it also includes buttons, with multiple buttons slidably connected to the front right side of the display screen.

[0009] In a preferred embodiment of the present invention, the detection assembly includes a light source, a first bracket, a filter, a detector, and an electric push rod. The light source is connected to the inner left side of the detection box, the first bracket is connected to the bottom of the detection box, the filter is snapped onto the first bracket, and two electric push rods are connected to the inner right side of the detection box. The detector is connected between the telescopic ends of the electric push rods.

[0010] In a preferred embodiment of this utility model, the mounting assembly includes a second bracket, a motor, a rotating frame, a mounting frame, and fixing screws. The second bracket is connected to the bottom of the test box and is located to the right of the first bracket. The motor is connected to the upper left side of the second bracket, and the rotating frame is rotatably connected to the upper part of the second bracket. The rotating frame is connected to the output shaft of the motor. Mounting frames are connected to the four parts of the rotating frame, and fixing screws are threaded onto each mounting frame.

[0011] In a preferred embodiment of this utility model, the rotating frame is cross-shaped.

[0012] Beneficial effects: 1. This utility model starts the light source and blocks the unnecessary light source by the filter, so that the light of the target wavelength can pass through and illuminate the antireflection film. At the same time, four different or the same antireflection films are rotated and detected in sequence. Thus, four different or the same types of antireflection films can be rotated to detect the transmittance under a specific wavelength. The operation is simple, there is no need to frequently replace the antireflection film, it is convenient to comprehensively evaluate the performance of the antireflection film, and improve the detection efficiency and accuracy.

[0013] 2. This utility model limits the position of the detector by rotating the limiting rod to reset and contact the sealing door. Then, the electric push rod is activated, which drives the detector to move, thereby adjusting the distance between the detector and the anti-reflection membrane. This allows the position of the detector to be adjusted before detection, reducing interference and improving the accuracy and reliability of the detection.

[0014] 3. This utility model allows the antireflective membrane to be disengaged from the sealing door by rotating the limiting rod, and then the sealing door to be opened by rotating it. Next, a suitable filter is snapped into the first bracket, and then four antireflective membranes of different or the same type are brought into contact with the mounting frame. Then, the fixing screw is rotated to move and fix the antireflective membrane, thereby fixing the antireflective membrane during the test, preventing the antireflective membrane from shifting or falling off, and improving the stability of the test.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] A device for detecting the transmission of antireflective coatings in a specific wavelength band, such as Figures 1-5 As shown, the device includes a testing box 1, a sealed door 2, a running light 3, a display screen 4, buttons 5, a testing component, and an installation component. The sealing door 2 is rotatably connected to the lower front part of the testing box 1. A damped rotating limit rod is provided on the upper front side of the testing box 1 to limit the sealing door 2. The running light 3 is connected to the upper left side of the testing box 1. The display screen 4 is connected to the right front side of the testing box 1. Six buttons 5 are slidably connected to the front right side of the display screen 4 for easy operation. The testing box 1 is equipped with a testing component for detecting the permeability of the antireflection membrane. An installation component for installing the antireflection membrane is provided at the bottom inside the testing box 1.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the detection assembly includes a light source 6, a first bracket 7, a filter 8, a detector 14, and an electric push rod 15. The light source 6 is connected to the inner left side of the detection box 1, and the first bracket 7 is connected to the bottom of the detection box 1. The filter 8 is snapped onto the first bracket 7. The electric push rods 15 are connected to the inner right side of the detection box 1, and the detector 14 is connected between the telescopic ends of the electric push rods 15.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting assembly includes a second bracket 9, a motor 10, a rotating frame 11, a mounting frame 12, and fixing screws 13. The second bracket 9 is connected to the bottom of the test box 1. The second bracket 9 is located to the right of the first bracket 7. The motor 10 is connected to the upper left side of the second bracket 9. The rotating frame 11 is rotatably connected to the upper part of the second bracket 9. The rotating frame 11 is connected to the output shaft of the motor 10. The rotating frame 11 is cross-shaped. The mounting frame 12 is connected to the four parts of the rotating frame 11, and the fixing screws 13 are threaded onto each of the mounting frames 12.

[0025] When it is necessary to test the transmittance of antireflective coatings at a specific wavelength, this device can be used. The test chamber 1 is brought into contact with a table or work surface. Then, the limiting rod is rotated to disengage from the sealing door 2. The sealing door 2 is then rotated to open. Next, the appropriate filter 8 is snapped into place with the first bracket 7. Then, four antireflective films of different or the same type are brought into contact with the mounting frame 12. The fixing screw 13 is then rotated to move and fix the antireflective film. This allows the antireflective film to be fixed during testing, preventing displacement or detachment and improving the stability of the test. After fixing, the device is rotated in the opposite direction... The sealing door 2 is closed, and then the limiting rod is rotated to return to contact with the sealing door 2 for limiting. Then, the electric push rod 15 is activated, which moves the detector 14, thereby adjusting the distance between the detector 14 and the antireflective film. This allows for adjustment of the detector 14's position before detection, reducing interference and improving detection accuracy and reliability. After adjusting to the appropriate position, the electric push rod 15 is closed, and the light source 6 is activated. At this time, the running light 3 illuminates, and the filter 8 blocks unwanted light from the light source 6, allowing light of the target wavelength to pass through. The light is then irradiated onto the antireflective coating at the corresponding location. The detector 14 then detects parameters such as the transmittance and reflectance of the antireflective coating. The detected data is displayed on the screen 4. The screen 4 is operated via buttons. The transmittance of the antireflective coating is then evaluated based on the detected data. Simultaneously, the motor 10 is activated, driving the rotating frame 11 to rotate. The rotating frame 11 is cross-shaped, causing the mounting frame 12 to rotate. This allows four antireflective coatings of different or the same type to be detected sequentially, enabling the rotation of four different or the same type of antireflective coatings within a specific wavelength range. The method for performing penetration testing on antireflective membranes is simple, requires no frequent replacement of the membrane, facilitates comprehensive evaluation of membrane performance, improves testing efficiency and accuracy, and is easy to use. After the test is completed, turn off the light source 6 and the motor 10. At this time, the running light 3 will turn off. Then, rotate the limit rod to disengage from the sealing door 2, and then rotate the sealing door 2 to open. Next, remove the filter 8, and then rotate the fixing screw 13 in the opposite direction to move it away from the antireflective membrane. Then, remove the antireflective membrane, and then rotate the sealing door 2 in the opposite direction to close it. Finally, rotate the limit rod to reset it and contact the sealing door 2 for limiting.
