With the development of display devices, the demand for optical films is also increasing. The production capacity of optical films is growing, and along with it, there is a large demand for testing optical films. In traditional measurements, optical films need to be cut manually and then placed in a backlight device for measurement. The disadvantages of this measurement method are obvious. The cutting size cannot match the device, and the edge position will inevitably be measured inaccurately during measurement. Moreover, only one film can be measured at a time, and there is no suitable place to store the film after measurement. At the same time, for rolled optical films, they cannot be completely fitted with the backlight due to warping, resulting in errors in measurement, which greatly hinders efficiency and accuracy.

A transverse chassis 5 is slidably installed on the transverse frame 4. The longitudinal bracket 6 is fixedly installed on the transverse chassis 5.
