Diffractive Optical Elements (DOEs)
DOE technologies are emerging in the optics industry. Its applications range from technical optics such as scanning and metrology to bioimaging and printing. DOEs are added to laser systems to control the incident beam’s phase and amplitude and to ‘shape’ the beam to a desired output pattern with distinctive functionality. It uses a surface complex microstructure to direct photons for specific functions.

Beam Splitter DOEs | Beam Shaper DOEs |
The collimated laser light is incident onto an array (1 x N or M x N) of Beam Splitter DOE to split the input beam into N beams. The N output beams make some separation angle with the Beam Splitter DOE and there exists the desired zero-order beam for an odd number of beams (N). The focusing lenses are often used to achieve the output at the desired working distance. Material: Fused Silica |
This setup comprises a laser source, Beam Shaper DOE, scan system/lens, and a working surface. The light passed through the Beam Shaper DOE distributes the Gaussian beam energy into a uniform intensity of either a circular or rectangular top-hat profile. Material: Fused Silica |
