Beam-splitters are optical components used to split input light into two separate parts. Beam-splitters are common components in laser or illumination systems. Beam-splitters are also ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation. Light can be split by percentage of overall intensity, wavelength, or polarization state.
Lasertec offers plate, cube, and specialty prism Beam-splitters in a variety of anti-reflection coatings or substrates. Standard Beam-splitters, which split incident light by a specified ratio that is independent of wavelength or polarization state, are ideal for illumination subassemblies or as one way mirrors. Dichroic Beam-splitters, which split light by wavelength, are often used as laser beam combiners or as broadband hot or cold mirrors. Non-Polarizing Beam-splitters, ideal for laser beam manipulation, split light by overall intensity. Polarizing Beam-splitters, often used in photonics instrumentation, split light by polarization state. Lasertec’ anti-reflection coatings are designed for the Ultraviolet (UV), Visible, of Infrared (IR).
