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 generic version of structured light dot matrix DOE is divided into two categories: adaptive collimator lens ("collimated DOE" for short) and non-collimator lens ("non-collimated DOE" for short), for customers with different demands, providing the best cost-effective projector products.

The right side is collimated DOE with 9*10 spectral dot matrix, providing high efficiency and SNR.
