Description
Please refer to the new product list that includes all thin film polarizers offered by EKSMA Optics.
- Provide the achievement of strictly linear polarization of laser radiaton
- Utilize the polarization wich occurs on reflection from a plane surface
- Rs/Tp:>99.5/95.0% for standard thin film polarizers
- Rs/Tp:>99.5/99.0% for high transmittance thin film laser polarizers
- Ts<0.2%, Rp<0.2% for ultra high transmission thin film polarizers
- Tp>98%, Ts<0.1% for thin film polarizers with high extinction ratio
- High damage threshold reaching 10 J/cm2
- Extinction ratio 200:1 (for standard, high and ultra high transmission thin film polarizers), 1000:1 (for thin film polarizers with high extinction ratio)
Thin Film Polarizers separate the s- and p-polarization components. They are designed for use in high energy lasers. Due to high damage threshold, reaching 10 J/cm2 @ 1064 nm 8 ns, Thin Film Polarizers are used as an alternative to Glan Laser Polarizing Prisms or Cube Polarizing Beamsplitters.
Typical applications are intracavity Q-switch hold-off polarizer or extracavity attenuator 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). Typical polarization ratio Tp/Ts is 200:1.
Standard size is up to Ø50 mm (2”), while max. available dimensions are 100×200 mm. For optimal transmission a Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment. For Rectangular Thin Film Polarizers, visit here.
