Lecture

Anti-Reflection Layer Thickness

Description

This lecture covers the calculation of the minimum thickness required for an anti-reflection layer to work, considering an incoming ray with a wavelength of 600 nanometers and normal incidence angle. By analyzing the phase difference between reflections at different interfaces, the instructor explains how to determine the optimal thickness for canceling out reflections. Through detailed calculations and explanations, the lecture concludes with the derivation of the minimum thickness as 120 nanometers.
