Femtoline Thin Film Laser Polarizers (Round) 1030nm 420-1248HT
Description
Femtoline Thin Film Laser Polarizers (Round) are optical components designed to separate s- and p-polarization components. These polarizers offer an excellent alternative to Glan laser polarizing prisms or cube polarizing beamsplitters, featuring a high damage threshold of up to 100 mJ/cm² at 800 nm with a pulse duration of 50 femtoseconds.
EKSMA Optics offers standard thin film laser polarizers with Rs/Tp>99.5/95.0%, high transmission thin film laser polarizers with Rs/Tp>99.5/99.0%, and thin film polarizers with high extinction ratio (HE series) with Tp>98% and Ts<0.1%.

Frequently Asked Questions
Thin Film Polarizers are designed for use in high energy lasers as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters. Typical applications are intracavity Q-switch hold-off polarizers or extracavity attenuators for Nd:YAG lasers.
Thin Film Polarizers can be used at an >40° angle of incidence, but polarization is most efficient and appears in a broad wavelength range at 56° AOI (Brewster angle).
The standard size for Thin Film Polarizers is up to Ø50 mm (2”), while max available dimensions are 100×200 mm.
The laser damage threshold for Thin Film Polarizers is high, reaching 10 J/cm² @ 1064 nm 8 ns.
The typical polarization ratio TP/TS is 200:1.
