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 coatings on both sides of the polarizer. They can be optimized for highest transmission of p polarization Tp>94% or best contrast of polarizations Tp:Ts>20:1.
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 best contrast of polarizations Rs:Rp>60:1. Moreover, the AR coated side of a polarizer can have 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.
