Attention! You can customise this product to your needs.
The optimal working angle for Broadband polarizers is is AOI=72° (±2°). We offer 4 types of Broadband (Ultrafast) Thin film polarizers. Polarizers work by transmitting p-polarized and reflecting s-poarized beam component.

TRANSMISSION POLARIZERS - have polarizing coating on the input face while the output face is AR coated for p polarization. They can be optimized for highest transmission of p polarization Tp > 94% or for best contrast of polarizations.

REFLECTION POLARIZERS - have polarizing coating on the input face while the output face is AR coated for both s and p polarizations. They can be optimized for highest reflection of s polarization Rs > 98% or for best contrast of polarizations Rs:Rp>60:1. Moreover, the AR coated side of a polarizer has wedge to minimize ghosting.

Standard thin film polarizers are designed for optimum performance in the 750 - 850 nm or 980 - 1090 nm range. Design of custom wavelength range is also available.
varna Efficiently separates the s and p polarization components
varna Many Broadband (ultrafast) Thin Film polarizers are available from STOCK with fast delivery
varna Available in dimensions up to 160x50 mm
