WebA grating consists of many slits, or lines, close together. In a grating, the spacing between adjacent lines is constant. Gratings are also used to produce interference patterns. When … WebMar 22, 2024 · If a beam is focused beyong the grating, it forms the focused image of a spectrum at the distance of the undiffracted focused beam. As long as the incoming beam has high spatial coherence, the wavelengths are well separated at that spectrum image. Of course aberrations can occur. The main reason a collimated beam is usually used to …
