GB/T 25273-2025 "Method for Determining Haze and Luminous Transmittance of Films for Liquid Crystal Displays (LCD) - Integrating Sphere Method" is applicable to the testing of haze and luminous transmittance of films used in LCDs, replacing the previous outdated standard. The core instrument is an integrating sphere haze and transmittance tester that meets the required specifications, featuring a stable light source system and a precise light signal detection module. Under specified environmental conditions, the sample is placed in the instrument, and the haze and luminous transmittance values are calculated by measuring the ratio of scattered to directly transmitted light, providing a basis for controlling the optical performance of the films.
