Polarizing Beamsplitter Cube
This Polarizing Beamsplitter Cube is cemented two right angle prisms, with polarization beamsplitting coating on the internal hypotenuse surface and all other 4 surfaces AR coated. Polarizing Beamsplitter Cubes provide a high degree of polarization over a broad visible or near IR spectral range.
Features of Polarizing Beamsplitter Cube
- Both Laser line and Broadband Coating
- High Extinction Ratio: Tp/Ts up to 3000:1
- Wavelength Ranges from 450 to 2020 nm
- Available Mounted & Unmounted
