High-Damage Threshold Thin-Film Polarizer, 1030 nm, 55.4° AOI
PP-UVFS-25.4-3.0-BTFP17Design Tools
Complete Your Setup
Overview
This high-damage-threshold thin-film polarizer is built on an ion-beam-sputtered (IBS) multilayer coating for exceptional laser-induced damage resistance, cleanly separating the s- and p-polarization components of a beam with high transmission, a high extinction ratio, and low absorption loss — engineered for high-energy and high-average-power laser systems.
Applications
- High-power & high-energy laser systems
- Pulse conditioning & polarization control
- Laser processing & micromachining
- Optical experiments & metrology
