Structured light diffractive optical elements (DOE) are specially designed to split or shape a single laser beam to cover a large field of view.
By upgrading our production facilities, Holo/Or now offers high-angle, high-quality, high-efficiency Beam Splitters and Beam Shapers DOE for both low and high-power applications ranging from mW to KW range.
Our DOE are made of either UV-grade Fused Silica, or low cost option such as polymer on glass or injection molded plastic. The main plastic types are: Polycarbonate, PMMA, Zeonex and Zoner.
Typical applications include structured light 3D sensing, LIDAR and light projection.
Holo/Or is happy to launch this brand new High-angle Diffractive Optical Elements (DOE) product line to meet our customers’ demands.

Beam Splitter
Target DOEs
Multispot DOEs with the remark “target” is an element that produces a number of spots building a typical target, refer also to below image.
Random DOEs
Multispot DOEs with the remark “random” have a random pattern of spots, when 50% of the dot matrix are potential spots and will be “on”, and this is determined by a randomizing algorithm.
Standard MS DOEs
Multispot DOEs without any additional remark, show a homogenous distribution of the spots, as shown in the image below:
