SUMMARY
The discussion focuses on calculating the index of refraction for a coating and its required thickness for a glass lens with an index of refraction of 1.40 at a wavelength of 600 nm. The initial calculation provided by a user suggests a coating index of refraction of 1.183 and a thickness of 126.8 nm. Verification of these values can be achieved through the 'λ/4 argument' method, ensuring equal reflection coefficients at both interfaces.
PREREQUISITES
