How Thin Film Interference Works in Optical Coatings

Lenses & Optical ComponentsBy giai2026-10-14

Thin film interference works by splitting one light wave into two or more reflected waves, one from the top surface of a film and one from the bottom. Because the second wave travels an extra optical path of about 2nd cos θ, and each reflection may add…

What Is Angle of Incidence (AOI) in Optics?

Optical Materials & InfraredBy giai2026-10-14

A narrowband optical filter may meet its wavelength specifications during laboratory testing but behave differently after installation in an optical system. One possible reason is a difference in the angle at which light reaches the filter. This angle is known as the angle of incidence…
