Being the cubic measure phase holographic diffraction grating device in order to use cubic measure

摘要

The cubic measure phase holographic diffraction grating device is offered. As for this cubic measure phase holographic diffraction device, light of very short wave length, for example, with the light in the ultraviolet (ULTRAVIOLET RADIATION) spectrum territory it can be optimized in order to use. This device includes the cover and the baseplate, both of the cover and the baseplate are formed from glass material. Layer of the gelatin material, is arranged with the cover component and the baseplate component, the variable refractive index which was formed holographic is formed by this layer, provides interference pattern. The gelatin material has had the thickness of 0.5 micron - 1 microns, as for this thickness, although the light in the ULTRAVIOLET RADIATION spectrum territory is diffracted it is suited, it is long-lived, is very efficient.
