In this way, by moving the first slider structure 42 and the second slider structure 43 toward each other along the linear guide structure 41, the first clamping portion 310 on the first clamping member 31 and the second clamping portion 320 on the second clamping member 32 cooperate with each other to clamp the sample 10 to be tested. On this basis, the horizontal displacement of the sample 10 to be measured can be realized by maintaining the relative positions of the first clamping member 31 and the second clamping member 32, in other words, the relative positions of the first slider structure 42 and the second slider structure 43, and moving the two structures to the same side along the linear guide structure 41. Similarly, the relative positions of the first slider structure 42 and the second slider structure 43 are maintained, and the telescopic structure 44 is driven to extend or contract, so that the whole clamping device 3 formed by the first clamping piece 31 and the second clamping piece 32 can move up and down, and the vertical direction of the sample 10 to be measured can be driven to move.

It can be understood that the light transmittance measuring system of the present invention is not restricted to the specific form of the light intensity detecting device 5. In some embodiments, as shown in fig. 1, the light intensity detecting device 5 includes an integrating sphere 51 and a light intensity detector 52, a detection portion of the light intensity detector 52 is disposed on an inner wall of the integrating sphere 51, and an entrance window 510 of the integrating sphere 51 is located on the light path and faces the light source device 1.

For ease of understanding, the integrating sphere will be briefly described below. The integrating sphere is also called a light-passing sphere and a photometric sphere and is a complete hollow spherical shell. The integrating sphere is mostly made of a metal material, coated with a white highly diffuse reflective layer (usually magnesium oxide or barium sulfate) on the inner wall, and the dots on the inner wall of the sphere are scattered uniformly. The light enters from the entrance window 510 of the integrating sphere and is subjected to multiple diffuse reflections, so that the light flux reaching the light intensity detector is very uniform and almost independent of the spatial or polarization characteristics of the light, and the detected light power is only dependent on the total incident light power. In this way, the test light emitted from the light source device 1 passes through the transparent sample 10 to be measured and then enters the integrating sphere 51 from the entrance window 510 of the integrating sphere 51, and then is subjected to multiple diffuse reflections, the luminous flux reaching the detection portion of the light intensity detector 52 is very uniform, and the detected optical power is only related to the incident optical power from the entrance window 510, so that the light intensity detection device 5 can accurately measure the transmittance of the sample 10 to be measured.

In some preferred embodiments, the light intensity detecting device 5 further includes a standard reflecting plate 54 and a light trap 53 disposed inside the integrating sphere 51. The surface coating material of the standard reflecting plate 54 is the same as the internal reflecting coating of the integrating sphere 51, and magnesium oxide coatings can be adopted, so that the full emission can be generated after part of light reaches the standard reflecting plate 54. The standard reflection plate 54 may be disposed at a position of a central rear sidewall of the integrating sphere 51, and may slide downward by an angle of 1 to 10 degrees with respect to the optical path. The light trap 53 is closely attached to the outer wall on the rear side of the integrating sphere 51, and the light trap 53 is located on a horizontal line passing through the entrance window 510 of the integrating sphere 51, i.e., on the optical path. The optical trap 53 is coated internally with magnesium oxide or other diffusely reflective material. The detection light passes through the transparent or semitransparent sample to be detected and then generates stray light, and the light trap 53 is arranged on the light path to absorb the stray light, so that the detection accuracy is improved. When no light enters the entrance window 510 of the integrating sphere 51, the standard reflecting plate 54 and the light trap 53 can absorb all the light inside the integrating sphere 51 to prepare for the next transmittance test.

In some preferred embodiments, the entrance window 510 of the integrating sphere 51 is of a variable aperture construction, as shown in FIG. 1. In this way, the size of the entrance window 510 can be controlled to be suitable for the size of the detection site of the sample 10 to be detected, so as to obtain the optimal transmittance measurement effect. As an example of a practical implementation, the aperture-variable structure of the entrance window 510 may refer to a structure of a camera aperture, for example, the structure includes a plurality of opaque arc plates circumferentially arranged, a rotating pair is disposed at a bottom end of each arc plate, an arc track is disposed in the middle of each arc plate, and a cylindrical pin is disposed at a bottom end of each arc plate to drive the arc plate to move along the arc track and change the opening and closing of the arc plate. The overlapping center of the multiple arc segments can be considered as the clear aperture, with the smallest aperture being up to 0.1mm.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
