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.

Standard high angle STRUCTURED LIGHT DOE
Our standard list of structured light DOE is constantly growing with new DOE available for mass production.
Standard thickness for Fused Silica/ polymer on glass is 1.5 mm.
Standard thickness for plasric is 0.6 mm; All standard plastic DOEs do not have antireflective coating.
All dimentions can be adjusted as per customer specifications.
Multispot DOEs with the remark “target” is an element that produces a number of spots building a typical target, refer also to below image.
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:
Full angle [deg]
Number of spots

For custom DOEs
If you are interested in custom DOEs, please provide the following data:
- Description of application
- Beam definition (diameter, input mode, divergence)
- DOE dimension – if some specific values are needed
- Working distance
- Requested output shape at working distance
- Special needs (high efficiency, high homogeneity, AR coating)
- Quantity for samples and serial production
