Beamsplitter
Beam splitters separate a beam of light by wavelength, power, or polarization into two orthogonal beams. The properties of the divided beams depend both on the beam splitter coating and on the mechanical characteristics of the plate or cube upon which it has been coated. Beam splitter coatings can even be applied to our wedged and plane parallel substrates for OEM applications.

Beamsplitter Beam Splitters 100optics
Material: K9 or ZF glass Dimensional Tolerance: ±0.2 mm Surface Quality: 60 / 40
A polarizing cube beamsplitter separates a randomly polarized beam into two orthogonal linearly polarized components: S polarization is reflected at 90 degrees, while P polarization is transmitted. Each consists of a pair of high-precision, high-tolerance right-angle prisms bonded with a dielectric coating on the hypotenuse of one prism. Baijing Optoelectronics offers high-quality beamsplitters.

Non-polarizing beamsplitter (NPBS) Beam Splitters 100optics
Material: K9 or ZF glass Dimensional Tolerance: ±0.2 mm Surface Quality: 60 / 40
Made by bonding two precision, high-tolerance right-angle prisms, with a metal-dielectric coating on the hypotenuse of one prism. The coating has low polarization dependence, keeping S- and P-polarized transmission and reflection within 6% of one another. The source states that the incident polarization is therefore unchanged.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
