Waveguides for AR/MR

For several years, NIL Technology has delivered masters for augmented and mixed reality (AR/MR) to some of the biggest players in the industry. 

We offer masters and sub-masters with blazed gratings, slanted gratings, and binary gratings. All three types of gratings can be combined in any ways and without any design constraints.

Surface relief waveguides

Surface relief waveguides for AR/MR are see-through waveguides, typically on high-refractive index glass. The waveguide includes surface relief gratings for in-coupling of the image signal from a projector, expansion in x and y, and out-coupling.

Typically, blazed- and slanted gratings are used for the coupling of light into the waveguide, and binary and slanted gratings are used for the pupil expansion and the out-coupling of the light.
