In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance be… 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.
