Complete Your Setup
Overview
This high-power thin-film polarizer uses an advanced multilayer coating to separate the s- and p-polarization components of a beam, providing high transmission and a high extinction ratio with low absorption loss — built for the power densities of high-energy laser systems.
Applications
- High-power laser systems & pulse conditioning
- Optical experiments & metrology
- Microscopy & imaging
