Broadband Non-Polarizing Beamsplitter Plate | SIMTRUM Photonics Store

Broadband non-polarizing beam splitter plates is used to split or combine light spectrum in UV, VIS, or IR wavelengths. The polarization of the outgoing beams remains the same when the incoming beam is a varied polarized light. Being partial-reflective coated mirrors, but often used with the incident of angle at 45°, plate beam splitters consist of a thin plate of optical glass with a different type of coatings. The thin film coating determines, typically, to reflect or transmit the incidence light according to its split ratio.

BK7 is the most common optical glass used in high-quality optical components as it is a hard glass that can withstand a variety of physical and chemical exposure. Relatively scratch and chemical resistant, it has a low bubble and inclusion content, therefore making it an ideal choice for precision lenses. It is the ideal choice for general purpose visual and NIR applications as it has excellent transmission.
