¿µ¹® ³»¿ë¿ä¾à This standard presents a comprehensive measurement method and procedure that combines interferometry-based phase measurement, spectral measurement, and angle-dependent measurement techniques to evaluate the special optical characteristics of metalenses, such as chromatic aberration, efficiency, and horizontal field of view. Specifically, it provides standard sample preparation methods for metalens specimens; multi-wavelength focal length variation measurement for chromatic aberration; focal spot intensity ratio measurement for efficiency; and angle-dependent measurement for horizontal field of view. Additionally, for each measurement item, the standard provides detailed optical system configurations, environmental condition controls, data acquisition and analysis methods. The collected data is statistically analyzed to offer quantitative performance indicators necessary for the commercialization of metalens technology.
