Description and Application

A laser beam splitter is a diffractive optical element that divides a single laser or LED light beam into multiple beams. Each beam retains the characteristics of the original beam, and these beams can be arranged either in a regular or irregular pattern. Depending on the diffraction pattern, the beam splitter can create one-dimensional beam arrays and two-dimensional beam matrices, or be designed to produce specific beam patterns according to actual needs. A one-dimensional laser beam splitter divides a single laser beam into multiple beams diverging at different angles in a particular plane, forming multiple focal points in a plane perpendicular to the propagation direction. The beam splitter can split single-mode or multi-mode lasers, accurately control the beam divergence angle, and is suitable for incident light wavelengths from ultraviolet to infrared. It can be used in fields such as multi-beam material processing, laser illumination, machine vision, 3D sensing, and fiber coupling.
