With the development of coating technology, the application of optical film is increasingly widespread, involving defense, communications, energy and other fields. Among all optical films, antireflective films play an important role and are the most commonly used optical films. Therefore, how to use an optical film having different characteristics to obtain a desired glass transmittance is the subject of current research. In this paper, the coated glass with different functional glass layers has been modulated ZEMAX® software, and the transmittance of the coated glass were analyzed in different wavelengths.
