General Optics
Polarizer-Analyzer-Attenuator
Achieve high-extinction ratio polarized infrared laser beams with these "pile-of-plates" type polarizers, available in both air- and water-cooled forms.
These ZnSe and Ge optics are specifically designed to minimize the angular deviation and lateral displacement of the beam as they are rotated. An optional exit port for the rejected beam makes them compatible with high-power CW and pulsed lasers.
Polarizer-Analyzer-Attenuator Selection
Choose from a variety of configurations and aperture sizes. All standard units are post-mounted in a rotatable mount with a factory-set 360° angular readout dial.
