Home > Polarizing Optics > 14PUF - Broadband Ultrafast Thin Film Polarizers
broadband ultrafast thin film polarizers
Ideal for Femtosecond laser applications due to the low GVD
 
Works over Broad wavelength range
 
Separates the s- and p- polarization components
 
Standard Thin Film Polarizers are available from stock

Broadband (Ultrafast) Thin Film Polarizers are used for femtosecond lasers.
PLEASE NOTE: The optimal working angle is AOI=72° (±2°). We are offering 4 types of Broadband (Ultrafast) Thin film polarizers. Polarizers work by transmitting p polarization and reflecting s polarization.

TRANSMISSION POLARIZERS - have polarizing coatings on both sides of 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 AR coated side of 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. Design of custom wavelength range is also available.
