[0032] See also Figure 2-3 In this embodiment, the transverse slide rail 9 is a convex structure, and a groove adapted to the raised portion of the transverse slide rail 9 is opened at the bottom of the slider 603, and the raised portion of the transverse slide rail 9 is placed in the groove at the bottom of the slider 603, and the surface of the transverse slide rail 9 and the groove at the bottom of the slider 603 are both designed to be a smooth mirror structure.

[0033] It should be noted that the transverse slide rail 9 can support the slider 603 and the fixed plate 601, and at the same time can limit the sliding position of the slider 603 so that it can only move along the track of the transverse slide rail 9.

[0034] When using this utility model:

[0035] The staff first places the film body 3 (ITO film) to be tested in the product positioning slot 2, and then starts the spectrometer 8 and the servo motor 12. The spectrometer 8 can perform corresponding tests (transparency, reflectivity, absorptivity, film thickness, uniformity, etc.) on the bottom of the film body 3, and display them on the display screen 4. After the servo motor 12 is started, it can drive the screw 1201 to rotate through the power output shaft. When the screw 1201 rotates, it can drive the movable block 2 701 to move in the movable slot 6022, and at the same time drive the sliding seat 7 to move longitudinally on the longitudinal slide rail 602, so as to drive the spectrometer 8 to move longitudinally through the sliding seat 7. When the spectrometer 8 is moving longitudinally, it can perform corresponding tests (transparency, reflectivity, absorptivity, film thickness, uniformity, etc.) on the longitudinal area of ​​the film body 3 at this position;

[0036] When the spectrometer 8 is being tested, the adjusting handle 5 can be rotated to drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, the movable block 604 can be driven to move. When the movable block 604 moves, the fixed plate 601 is synchronously driven to move laterally on the two transverse slide rails 9, thereby changing the transverse position of the spectrometer 8. When both the longitudinal position and the transverse position of the spectrometer 8 can be changed, the spectrometer 8 can be used to test various areas below the film body 3, thereby improving the accuracy of the test results.
