Custom Diffractive Optical Elements

Diffractive Optical Elements (DOEs) are optical components with a micro or nano structured surface, which diffracts light incident onto this surface. The placement, size and shape of these structured surfaces determine how the diffracted light will be affected. The term DOE is typically used to describe an optic that is designed to diffract a monochromatic incident light source into a specific image or pattern. DOEs are commonly used to split a single beam into multiple beams or to shape a beam into a specific pattern. DOEs can also be used to shape the output distribution of a laser beam into a specific distribution profile.

Diffractive Optical Element Function

Diffractive Optical Elements are progressively replacing traditional refractive optics. They are flatter, thinner, and lighter, contributing to smaller optical systems. By incorporating DOEs into the design, engineers are able to develop innovative, high performance, extremely robust, and accurate optical systems.
