Find what minimum thickness gives high reflectivity

Reference no: EM13673587

A thin film of cryolite (nc = 1.37) is applied to a camera lens (ng = 1.65). The coating is designed to reflect wavelengths at the blue end of the spectrum and transmit wavelengths in the near infrared. Find what minimum thickness gives high reflectivity at 490 nm and find what minimum thickness gives high transmission at 980 nm?
