Thin film laser optical polarizer
Altechna Co. Ltd.
* Transmission optimized polarizers have the same polarizing coating on both sides to achieve maximum 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 reflection 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.
