A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
Refraction. The bending of rays of light as they pass from one medium into another, e.g. from air to water, or from air to glass. Reflector ... Refraction. The bending of light rays by the glass element s inside a lens so that they converge and focus on a single plane in side the camera 's film or digital sensor.Scene. The place or environment viewed from camera position.hen light rays change path as they pass through one transparent object, such as a lens element, to the next. REFRACTION. As if this is not enough, there are more problems. When light travels from air to water it slows down as it meets the dense r medium..
