Custom Beam SPLITTER products
The Diffractive Beam Splitter (or dot generator) 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.
Typical applications of Optical Beam Splitters include: Laser scribing such as in solar cells or panels, Laser dicing, Laser perforation, Medical/aesthetic applications such as skin treatments, 3D sensing & projection. Read more about Multispot Beam Splitters in the application notes.
In this section, we present our standard list of custom shape beam splitter. If you can not find the exact spec required we can design custom elements with your specs as a part of our custom design and manufacturing capabilities.
