| According to the total reflection phase-change theory designed Fresnel size Ling phase-delay delay production on the incident angle is not sensitive to changes in the structure of the angle. According to the film's polarization effects, the film features from the matrix, in the two-Ling total reflection surface evaporation method of optical media film broadens the Fresnel Ling size of the achromatic phase delay width. In ML_EB900-coating machine suitable to control the deposition conditions preparation achromatic phase retardation film, laboratory test results showed that: 530 ~ 700 nm wavelength range can be 90 ° phase delay, and the maximum deviation of less than 0.7 ° . |
