Dichroic mirrors separate or combine two or more beams of different wavelengths in the desired ratio and enable process monitoring on the operating level in several wavelength ranges, as well as beam diagnostics. Their complex design enables multiple transmission and reflection. A beamsplitter (beam splitter) is a precision optical component used to divide a beam of light into two paths—or work in reverse as a beam combiner to merge multiple beams into one. While they are often characterized by their splitting ratio (e. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). Different types of beam splitters exist, as described in the. Thorlabs offers a wide range of optical beamsplitters. Beamsplitters are common components in laser or illumination systems.
