Thin Film Polariser, High Contrast, 355nm

Manufacturer's part number :


Manufacturer Altechna


Description :

High contrast Thin Film Polarizers (TFP) at 355nm are made using advanced Ion Beam Sputtering (IBS) coating technology. UVFS dielectric coated high contrast thin film polarizers separate the s- and p-polarization components of high energy laser beams. Due to very low losses they are perfect for intra and extra cavity usage. Typical polarization ratio of these polarizers is well above 1000:1 (Tp:Ts).
