Optical film light transmission characteristics

アイテス

At Aites Co., Ltd., we conduct "optical film analysis." Optical films used in smartphones and other devices have various functions depending on their structure and materials. We measured the light transmittance of privacy protection films at different angles and combined cross-sectional observation with Raman analysis to investigate the mechanism of function manifestation. By investigating the transmittance characteristics of privacy protection films using angle-variable spectrophotometry, we were able to analyze the mechanism of function manifestation through cross-sectional observation and Raman analysis. At Aites, we provide consistent evaluation and analysis from material properties to the mechanisms of function manifestation.
