Laser Beamsplitter

Beamsplitters are optical devices used for splitting a beam of light into two or more different portions based on wavelength, polarization, or intensity. They are commonly used in laser and illumination systems, fluorescence applications, and optical interferometry. Laser beamsplitters, both polarizing and nonpolarizing versions, can take many forms, including glass or silica plates and cubes (usually two triangular prisms glued together). Another design uses dielectric or metallic-coated mirrors for splitting light beams.

What to consider when choosing a laser beamsplitter?

Although laser beamsplitters are offered for the entire spectrum from UV to IR, specific coatings are optimized for use with different parts of the spectrum. Careful consideration of the device’s reflection and transmission values will give a truer idea of how well it will actually perform in the lab.
