Product Description
Our broadband dielectric beamsplitters are designed to provide general purpose laser beamsplitting 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.
