| Product Description |
Plane Ruled Gratings
Ruled diffraction gratings are produced by ruling a series of closely spaced, straight parallel grooves into an optically flat aluminum coated substrate, known as the “master grating.” Precise, interferometrically-controlled ruling engines utilize a very fine diamond tool to form a sawtooth-shaped groove profile at a given angle (commonly referred to as the blaze angle) on the surface of a prepared substrate.
The replication process begins with the surface contour of a ruled master grating being vacuum deposition-coated with an extremely thin separation layer. An aluminum coating is then deposited on top of this separation layer. Then, an epoxy-coated flat glass substrate is placed on top of the layer-covered master, duplicating the grooved surface. The combination is cured and the process is finished when the replicated grating is separated from the master grating.
