Laser Damage Threshold, J/cm²	>10J/cm² for 10 ns pulses @ 1064 nm typical
Parallelism, arcsec	<30 arcsec
Substrate Material	UVFS
Surface Quality, S-D	20/10
Thickness Tolerance, mm	±0.2 mm

Description

Details

These high contrast Thin Film Polarizers (TFP) 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 (T_p:T_s). For optimal performance, high contrast Thin Film Polarizer should be mounted in an appropriate holder alowing angular adjustment.

Features

Made using IBS technology
T_p:T_s >1000:1
High T_p, low absorption & scattering
No aging effects due to the negligible porosity of the coatings
