Femtoline Polarizing Optics
02
Thin film laser polarizers (TFP) coated for 343 nm, 515 nm, 800 nm, 780-820 nm, 1030 nm, 1010-1050 nm wavelengths. We also offer a wide choice of zero order optically contacted or air-spaced, dual wavelength, multiple order and low order waveplates made from high quality crystalline quartz. This chapter also includes group velocity delay (GVD) compensation plates made of Calcite crystal, polarization plane rotators and variable attenuators for femtosecond linearly polarized laser pulses.
Motorized variable attenuators with ø 22 mm clear aperture, composed of thin film polarizers, half waveplates and opto-mechanics for easy setup. Motorized rotation of the waveplate allows continuous variation of the intensity ratio of the output beams.
Variable attenuator / beamsplitter is made of kinematic mount with polarizer holder, equipped with thin film Brewster type polarizer and quartz half waveplate.
Thin Film Polarizers (Round) seperate s- and p-polarization components. They can be used as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters due to the high damage threshold reaching 100 mJ/cm2, at 800 nm, 50 fsec.
Manual and motorized attenuators providing continuous beam splitting over 750-850 nm and 980-1080 nm broadband wavelength ranges. Consist of two thin film polarizers and a zero order air-spaced waveplate mounted into precision opto-mechanics.
Variable attenuator / beamsplitter is made of kinematic mount with polarizer holder, equipped with thin film Brewster type polarizer and quartz half waveplate.
Thin Film Polarizers (Rectangular) seperate s- and p-polarization components. Thin Film Polarizers can be used as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters.
Zero Order Plates are comprised of two different plates cut parallel to their optical axis. This construction makes plates less dependent on temperature.
Low Order Plates are less temperature sensitive and temperature dependent than Multiple Order Plates. These plates are suitable for high power applications.
Divides laser beam into two parallel beams of manually adjustable intensity ratio, large dynamic range, negligible transmitted beam deviation, high optical damage threshold.
