Description

Featuresthese high contrast thin Film Polarizers (tFP) are made using
advanced Ion Beam sputtering (IBs) coating technology.

• Made by IBs technology• tp:ts >1000:1

UVFS dielectric coated high contrast thin film polarizers separate thes- and p-polarization components of high energy laser beams. due tovery low losses they are perfect for intra and extra cavity usage.

• High tp, low absorption & scattering• No aging effects due to the negligible porosity of the coatings

typical polarization ratio of these polarizers is well above 1000:1(tp:ts). For optimal performance, high contrast thin Film Polarizer
should be mounted in an appropriate holder allowing angularadjustment.
We offer two types of high contrast polarizers - Brewster type and 45°100100HCBTFP 1064 nm / 54°

8 ns. Brewster type thin film polarizers are used as an alternative toglan-taylor laser polarizing prisms or cube polarizing beamsplitters.
Typically, BK7 or UVFS dielectric coated Brewster type thin filmpolarizers separate the s and p polarization components of highenergy laser beams and are intended for intra and extra cavity usage.
typical extinction ratio tp/ts is 200:1 and it is achieved at 56° aoI(Brewster angle). For optimal transmission Brewster type thin film
polarizers should be mounted in an appropriate holder for angularadjustment.

We are offering 4 types of broadband (Ultrafast) thin film polarizers.
Polarizers work by transmitting p polarization and reflecting spolarization.
TRANSMISSION POLARIZERS - have polarizing coating on the input
face while the output face is ar coated for p polarization. they canbe optimized for highest transmission of p polarization Tp>94% or forbest contrast of polarizations tp:ts>20:1.
