Femtoline Polarizing Optics
Femtoline polarizing optics section includes thin film laser polarizers coated for 343 nm, 515 nm, 800 nm, 780-820 nm, 1030 nm, 1010-1050 nm wavelengths. We also offer a wide choice waveplates – zero order, multiple order and low order – from high quality optical grade crystalline quartz for quick delivery. Other polarization components useful for ultrafast laser applications are: group velocity delay (GVD) compensation plates made of calcite crystals, 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.
