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.
Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters. [1] The name pellicle is a diminutive of pellis, a skin or film.

A trichroic prism assembly Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). [1] A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model.
The FBT splitter is one of the most common. FBT splitters are widely accepted and used in passive networks, especially for instances where the split configuration is smaller (1×2, 1×4, 2×2, etc.). [1] The PLC is a more recent technology. PLC splitters offer a better solution for larger applications.
As shown in Fig. 3a and 3b, the observer has a direct view of mirror M 1 seen through the beam splitter, and sees a reflected image M' 2 of mirror M 2. The fringes can be interpreted as the result of interference between light coming from the two virtual images S' 1 and S' 2 of the original source S .
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 ...
For a stack of plates, each reflection depletes the incident beam of s-polarized light, leaving a greater fraction of p-polarized light in the transmitted beam at each stage. For visible light in air and typical glass, Brewster's angle is about 57°, and about 16% of the s -polarized light present in the beam is reflected for each air-to-glass ...
