This standard specifies a method for the measurement of phase delay of cellulose triacetate (TAC) films using the swirl/spin photon method, which is suitable for measuring the surface phase delay and thickness phase delay of TAC films manufactured by the casting process. The standard provides a scientific Measuring method for the strain birefringence characteristics of Optical inspection films to ensure their performance Stability and conformity in display technology.
