High Extinction Ratio Thin Film Polarizers 2015-11-10

We are pleased to announce that we have extended the list of laser thin film polarizers by introducing our new High Extinction Ratio Polarizers. Polarizers with high extinction ratio are ideal solutions for laser cavities and optical systems where high purity polarization is needed.

 

These polarizers are made using our new Ion Beam Sputtered coating technology.

 

High Exctinction Ratio Polarizers feature:

High extinction ratio for transmitted light: Tp/Ts > 1000:1

Reflection efficiency: Rs > 99.8%

Transmission efficiency: Tp > 98%, Ts < 0.1%

High laser induced damage threshold: >3 J/cm2 at 10 ns, 1064 nm

We have designed thin film polarizers with high extinction ratio for the following wavelengths:

343 nm, 355 nm, 515 nm, 532 nm, 1030 nm, 1064 nm (see graph)
