The Diffractive Beam Splitter is a diffractive optical element used to split a single laser beam into several beams, each with the characteristics of the original beam (except for its power and angle of propagation). 

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 its output beams.

In this section, we present our standard list of custom shape beam splitter.
HOLO/OR offers, in addition to standard diffractive beam splitters, the possibility to choose the number of spots and their locations, as a part of its custom design and manufacturing capability.
