Dielectric Beamsplitter, Fused Silica, 76.2 mm, λ/20, 700-950 nm

The 30Q40BS.2 Broadband Dielectric Beamsplitter is made of fused silica, 76.2 mm in diameter, 12.45 mm thick, with a surface flatness of λ/20, and coated for 700-950 nm. Our broadband dielectric beamsplitters are designed to provide general purpose laser beam splitting and combining for visible through near infrared applications. Each coating is essentially achromatic across a wide spectral band so that a single optic will work for the entire range of a particular tunable laser, for several laser diode wavelengths, or for most visible laser wavelengths.
