Beam Splitter Flat
The flat beam splitter splits the incident light according to a certain proportion, which is independent of the wavelength and polarization state of the incident light. The polarizing plate beam splitter is designed to distinguish s and p polarization. The front surface of our flat beam splitter is coated with a beam splitting film that determines the beam splitting ratio, and the rear surface is a wedge-shaped surface and antireflection film to reduce ghost and interference effects.
Common beam splitters are used to separate or combine laser beams, and polarizing beam splitters are used to split or combine two beams of polarized light. The performance of the beam splitter mainly depends on its coating requirements. There are some ready-made products for you to choose from, and we also accept customization.
