Concentric Circles
A Diffractive Optical Element (DOE) is an advanced micro-nano optic that uses precision-etched surface structures to control laser phase. After passing through a DOE, the beam undergoes diffraction and interference to form designed patterns such as uniform spots, multi-lines, or dot matrices — the core technology for customized beam shaping.
Features
Excellent Gaussian distribution
No hot spots, stable imaging
Highly customizable
Uniform intensity distribution
