Differences Between Ruled and Holographic Gratings

Download Whitepaper
The efficiency curves of ruled and holographic gratings generally differ considerably, though this is a direct result of the differences in groove profiles and not strictly due to method of making the master grating. For example, holographic gratings made using the Sheridon method have nearly triangular groove profiles, and therefore have efficiency curves that look more like those of ruled gratings than those of sinusoidal-groove holographic gratings. There exist no clear rules of thumb for describing the differences in efficiency curves between ruled and holographic gratings; the best way to gain insight into these differences is to look at representative efficiency curves of each grating type.
