Description

Technical Field

[0001] The utility model relates to the field of filter testing, in particular to a uniformity testing tool based on filter spectral space. Background Art

[0002] A filter is an optical component whose main function is to allow light within a specific wavelength range to pass through while absorbing or reflecting light of other wavelengths. This selective light transmission property makes filters very useful in many fields and applications. The spectral uniformity of a filter is one of the important parameters for evaluating its optical performance. Through spectral spatial testing, it can be ensured that the filter's transmittance, peak wavelength, passband half-width, and cutoff band depth at different wavelengths meet the design requirements.

[0003] A filter-based colorimeter simulates the human eye's response to light by using red, green, and blue filters. These filters are matched to the CIE color matching functions and are used to measure the color of an object. A luminance meter, on the other hand, is used to measure the brightness of a light source. In a filter-based colorimeter, the light signal filtered by the filters is converted into an electrical signal by a detector, which then calculates the CIE tristimulus values ​​X, Y, and Z. These values, together with the brightness value measured by the luminance meter, are used to determine the color and brightness characteristics of an object.

[0004] In the prior art, a luminance meter is used when performing spectral space testing on filters. However, during the test operation, the luminance meter needs to be moved back and forth to test the filter in order to ensure the test effect. This causes inconvenience when testing batches of filters, thereby reducing the test efficiency. Therefore, a uniformity test tool based on the filter spectral space is proposed to solve the above problem. Utility Model Content

The inner wall of the slide groove 9 is provided with a slider 11. The slider 11 can slide inside the slide groove 9 to change the position of each group of mirror frames 2.

[0033] Reference Figure 3-Figure 5 The outer wall of the slider 11 is adapted to the inner wall of the slide 9. The positioning component includes a placement groove 10. The inner wall of the placement groove 10 is fixedly connected with a magnetic ring 16. The inner surface of the magnetic ring 16 is magnetically connected to the outer wall of the slider 11.

The end of the screw 12 away from the knob 13 is rotatably connected to the side wall of the slider 11. The end of the screw 12 is fixedly connected to the knob 13. The placement groove 10 is opened on the side wall of the fixed plate 8. There are several groups of placement grooves 10, and several groups of placement grooves 10 are equidistantly distributed on the side wall of each group of slide grooves 9. Each group of placement grooves 10 is connected to the slide groove 9. The stepped placement groove 10 can be used for adjusting the height of the slider 11.

[0034] Reference Figure 5The side wall of the mounting seat 15 is provided with a mounting groove 17, the inner wall of the mounting groove 17 is fixedly connected with a two-way telescopic rod 18, and the movable end of the two-way telescopic rod 18 is fixedly connected with a positioning plate 20.
