Knowledge Center/ Glossary/ Holographic Grating

Holographic Grating

A type of grating in which a sinusoidal "blaze" pattern is generated on the surface by exposing the grating (covered with photoresist) to an interference pattern. The sinusoidal variations in the interference pattern lead to the groove profile for the holographic element.
