Laser polarizationapp

3photon offers high contrast TFP plates: glass plates with dielectric polarizing coating. Thin film polarizers (TFP) can be a solution for many applications in optical devices and systems. For example, it can serve as an alternative for Glan type polarizers in laser systems, when a filtering of light source is needed. TFP plates are often designed to perform best at Brewster‘s angle. At this angle, the s- polarization beam is almost fully reflected from the surface while p- polarization travels through the element. This way the reflection losses are avoided for the transmitted polarization and does not require to have an anti-reflection (AR) backside coating for the p-polarization on the back surface.
