Grating-type beam splitter is a Optics element that can divide an incident beam into multiple spatially separated beams based on the principle of light Diffraction. Its core is a Grating with periodic micro-nano structure. By regulating the Grating period, groove type and depth, the incident light can be Diffraction to form beam-splitting light with controllable intensity in different levels and directions. The number, angle and energy proportion of each beam can be accurately designed. It has the characteristics of high beam-splitting stability, strong integration and low loss, and is widely used in Optical Communication, Laser radar, spectral analysis and other fields, achieve efficient beam splitting and spatial distribution.

Non-Grating beam splitter is a Optics element that does not rely on the principle of Grating Diffraction and splits an incident beam into multiple beams through mechanisms such as Refraction, Reflection or Interference. It uses prism groups, thin-film beam splitters, Microlens Array (MLA) and other structures to realize beam splitting based on Refraction distribution, partial Reflection or wavefront splitting of light. The number, angle and energy ratio of beam splitting can be controlled by the geometric parameters of the element. Compared with Grating devices, it has lower Dispersion and higher energy utilization in specific bands, and is suitable for Dispersion-sensitive scenarios, such as Laser Interference, Optics imaging, Optical Communication and other fields.
