A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.
The blue beam undergoes total internal reflection from the front of prism A and exits it through a side face. The remainder of the beam enters the second prism (B) and is split by a second filter coating (F 2) which reflects red light but transmits shorter wavelengths. The red beam is also totally internally reflected due to a small air-gap ...

A Wollaston prism. A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light.It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. [1]
A Thorlabs brand beam splitter. In March 2009, Thorlabs acquired optoelectronic components manufacturer Covega from Gemfire. Based in Jessup, Maryland, Covega was renamed Thorlabs Quantum Electronics (TQE) and its 40,000 sq. ft. space was expanded to 60,000 sq. ft. by 2014.
To equalize the dispersion, a so-called compensating plate identical to the substrate of the beam splitter may be inserted into the path of the vertical beam. [4]: 16 In Fig. 4b, we see using a cube beam splitter already equalizes the pathlengths in glass. The requirement for dispersion equalization is eliminated by using extremely narrowband ...
The original meaning of dichroic, from the Greek dikhroos, two-coloured, refers to any optical device which can split a beam of light into two beams with differing wavelengths. Such devices include mirrors and filters , usually treated with optical coatings , which are designed to reflect light over a certain range of wavelengths and transmit ...
By appropriately adjusting the mirrors and beam splitters, the fringes can be localized in any desired plane. The Mach–Zehnder check interferometer is a highly configurable instrument. In contrast to the well-known Michelson interferometer , each of the well-separated light paths is traversed only once.
