Diffractive optical elements is a kind of micro optics element used to control the light diffraction, phase, amplitude and directions. Coligh manufacturers lithography beam shaper, beam splitter, phase plate, precision gratings type DOEs.
They have the key features below:
- Ultilize photolithography processing
- Substrate material : Silicon, Fused silica
- Various functions like beam shaper (top-hat, annualr beams), beam splitting, beam homnogenization.
- We can improve diffraction efficienly through multilevel phase structure like 8 levels, 16 levels.
- Standard DOEs and custom DOEs are highly acceptable.
These Diffractive Optical Elements are widely used in the application like Medical Aesthetic ,3D sensing and imaging, multi-focal imaging, laser LiDAR and telecommunications.
