Plate-type beam splitter for high-power lasers.
Depending on the application, cube beam splitters may not be suitable, and instead, plate beam splitters are used. For the highest levels of wavefront and power handling, conventional coated plate types such as BK7 or fused silica are excellent choices. Spectral Optics offers various R/T ratios of standard plate beam splitters, all coated with dielectric coatings. These are designed for specific wavelengths and polarizations (S-polarized, P-polarized, or unpolarized), at 45° (or other incident angles). The backside is treated with anti-reflective (AR) coating.
