Technical FAQ
Configuration questions for Polarization Beam Splitter / Combiner
What wavelengths does the Polarization Beam Splitter / Combiner cover?
Principal Reflectance: Rs>99% and Rp<5%. Check the specification at your angle of incidence. Coating bands and grating efficiency curves are quoted at a reference angle, and both shift as that angle changes.
What size is the Polarization Beam Splitter / Combiner?
Dimension Tolerance: ± 0.2 mm · Thickness Tolerance: ± 0.2 mm. Clear aperture is smaller than the physical part, and the mount that holds it takes more again. Size the optic from the beam diameter at that plane, including the margin the mount consumes.
What is the Polarization Beam Splitter / Combiner made from?
Material: BK7 Grade A Optical Glass · Flatness: l/4 @ 632.8 nm per 25 mm. Substrate and coating decide thermal behaviour and cleaning method as much as optical performance. Confirm both before the optic enters a high-average-power or vacuum path.
