Beam Splitter

ØFunction:A diffractive beam splitter (or point generator) is a diffractive optical element used to divide a single laser beam into several beams, each having the properties of the original beam (except for its power and propagation Angle).

ØApplication:Laser marking such as solar cells or panels, laser cutting, laser perforation, medical/cosmetic applications such as skin care, 3D sensing and projection.
