Broadband (Ultrafast) Thin film polarizers

Description

Broadband (Ultrafast) Thin film polarizers for femtosecond lasers

We are offering two type of Broadband (Ultrafast) Thin film polarizers:
TRANSMISSION OPTIMIZED polarizers have the same polarizing coating on both sides to achieve maximal extinction ratio.
REFLECTION OPTIMIZED polarizers have polarizing coating on the input face while the output face is AR coated for both s and p polarizations. Moreover the faces of reflexion optimized polarizers are wedged.

Thin film polarizers are designed for optimum performance in the 750 - 850 nm , 980 - 1090 nm or any other wavelength range.
