WebA diffraction grating is a passive optical component that redirects light incident upon the surface at an angle that is unique for every wavelength in a given order. This redirection (or diffraction) is a result of the phase change of the electromagnetic wave as it encounters the regular, fixed structure of the grating surface. WebKaiser Optical Systems has developed and patented a multiplex grating structure-the Holoplex grating-in which two separate VPH gratings are sandwiched into a single optical element. Such a device allows manipulation of the spectrum that is difficult to do with classical grating technology. FIGURE 1.

Optical gratings consist of parallel, line-like structures, where the grating constant is the period of the grating. If coherent light falls on a grating, the light diffracted at the individual grating lines interferes and forms an interference pattern.
