Intensity Beamsplitter [Partially Transmitting, Partially Reflecting Mirror]
Splits only by intensity, dividing incident energy into fixed reflected and transmitted proportions, such as 50% reflection and 50% transmission. A beamsplitter is an important interferometer component widely used in lasers and fiber communication. It divides one beam into a source-described liang beams, or multiple beams, with properties identical to the source or partly identical for polarization splitting. Total split intensity equals source intensity if losses are ignored. Structure: a plane glass substrate with a single metal layer, such as aluminum or silver, or a dielectric coating. Coating thickness sets reflectance; a silver coating may provide 50% reflection and 50% transmission. Principle: partial reflection and transmission without wavelength or polarization selectivity. Slight phase differences or dispersion may occur, with metal absorption causing efficiency loss.

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.
