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 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.
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.

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 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.
The reticle image in this sight is produced by an optical collimator bounced off a beam splitter. The dot remains on the target even though the viewer's head is moved side to side A reflector sight or reflex sight is an optical sight that allows the user to look through a partially reflecting glass element and see an illuminated projection of ...
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 ...
