Broadband Dielectric Beamsplitter, UVFS, 25.4 mm, λ/10, 480-700 nm

The 10Q20BS.1 Broadband Dielectric Beamsplitter is made of fused silica, 25.4 mm in diameter, 6.1 mm thick, with a surface flatness of λ/10, and coated for 480-700 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.
