The DOE is designed to control the divergence angle of the beam and the shape of the light field, so that the beam forms a specific light intensity distribution and pattern;

UPhoton’s public version of structured light dot matrix DOE is divided into two categories: adaptive collimator lens and non-collimator lens, which provides the best cost-effective projector products for customers with different needs.

The left side is non-collimated DOE with 9*9 spectral dot matrix with high randomness and security.
