Low-Polarizing Cube Beamsplitters
OptoSigma Corporation
•Datasheet: OptoSigma Optical Components
- Metal-dielectric hybrid coatings
- Broadband neutrality
- Low polarization effect
- Low absorption
- Standard cubes from 5 to 20mm
These popular cube beamsplitters use a special combination of metallic and dielectric coatings on the internal splitting face to produce an even split in intensity with minimal polarization and minimal absorption. They make excellent beamsplitters for all but the most demanding applications. Beamsplitting is almost neutral over a broad range of wavelengths. Four wavelength ranges are offered. Two are broadband (400-700 & 600-900) and two are ultra-broadband (400-1000 & 800-1600). The reflected and transmitted beams each contain about 45% of the incoming intensity with only 10% absorbed. Also the s- and p- polarization components are within ±10%.
These beamsplitters are made from optical grade BK7. The faces are polished flat to λ/4 and two like prisms are cemented together to form a cube. Both pairs of sides are parallel to within 5arcmin. The four outer faces are broadband Anti-Reflection coated.
Four standard sizes are offered: 5,10,15 and 20mm. Larger sizes are available on request.
