Brewster-Type Thin Film Polarizers, 355nm Wavelength, 20*40 mm

Standard Brewster-type thin film polarizers are designed for applications including polarization separation. These elements offer modest extinction ratios Tp:Ts > 200:1, making them ideal for high power and UV applications. We offer standard and custom Brewster-type polarizers with wavelengths ranging from 230nm to 2000nm.
