Femtoline Polarizing Optics
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.
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.
