Description

Technical Field

[0001] The utility model relates to the technical field of optical element detection, in particular to an optical detection fixing device based on filter processing. Background Art

[0002] Filters are optical devices used to select the desired radiation band. One common feature of filters is that no filter can make the image of celestial objects brighter, because all filters absorb certain wavelengths, making objects darker.

[0003] After the filter is produced, it needs to be tested for light transmittance. Usually, a test device is used to emit a light source to illuminate the filter to measure its light transmittance data. During the detection process, multiple positions of the filter need to be tested. The tester needs to lower his head to manually adjust the position of the filter, and he needs to look up to observe the position of the test light source on the filter. The operation process is very inconvenient and is not conducive to improving the convenience of the tester. Utility Model Content

[0007] The clamping member comprises a supporting plate, a movable plate, a clamping plate installed on the side of the movable plate and a sliding member. The movable plate can slide on the supporting plate through the sliding member. The supporting plate is fixedly connected to the upper end of the movable rod.

[0008] In an embodiment of the utility model, a guide groove is provided on the inner wall of the sleeve, a pad is fixedly connected to the lower end of the movable rod, and a guide block capable of sliding in the guide groove is provided on the side of the pad.

[0009] In an embodiment of the present utility model, the lower end of the sleeve is detachably mounted on the detection platform via a connecting block.

[0010] In one embodiment of the utility model, the sliding member includes a slider, a slide groove opened on a support plate and a spring, one end of the spring is fixedly connected to one side of the slider, the other end of the spring is fixedly connected to the groove wall of the slide groove, the slider is slidably installed in the slide groove, and the slider is fixedly connected to the movable plate.
