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.
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 ...

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 red beam is also totally internally reflected due to a small air-gap between prisms A and B. The remaining green component of the beam travels through prism C. The trichroic prism assembly can be used in reverse to combine red, green and blue beams into a coloured image, and is used in this way in some projector devices.
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.
A K-mirror is a system of 3 plane mirrors mounted on a common motor axis which runs parallel to the chief ray of the system. If looking at the system parallel to the mirror surfaces, where only the edges of the mirrors remain visible, the middle mirror and the front and back mirror look like the backbone and legs of a capital-K; this illustrates the origin of the name.
