LASER COMPONENTS now offers beam splitters for CO2 lasers that maintain the polarization state of the laser beam for both the reflected and the transmitted partial beam: They are called "non-polarizing beam splitters."
The coating is applied to ZnSe "laser grade" substrates at high precision Rs,p [10.6 μm] = 50% ±1%. The coating consists of several layers, one of which is germanium; thus, the beam splitter is impenetrable for light in the visible range.
Non-polarizing beam splitters are suited for a laser power of <500 W/cm². Different standard components with a diameter of between 25.0 mm and 2" are available in stock and can be provided quickly for your tests.
