Diffraction grating - Wikipedia

Diffraction grating - Wikipedia

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

The central line is the undeflected beam of undispersed light at angle zero. The first order diffraction pattern appears on either side. A pure gas, when heated, emits light with specific wavelength (and thus specific energy per photon). Sodium and Mercury vapour lamps are viewed here through a grating.

on the wavelength of the incident light. Thus, a grating separates a beam of polychromatic light in its wavelengths components, so the grating is a dispersive tool. When a light beam is incident on a grating is diffracted in different beams. The beam corresponding to the direct transmission is called zero-order diffraction .

Resolvance of Grating - HyperPhysics Concepts

Resolvance of Grating. This approach to the resolvance of a grating has made use of the fact that the phase is a continuous variable which can be represented analytically, and that the differential of this variable is also well-defined. Since the Rayleigh criterion places the peak of one order at the first minimum of the adjacent order, the phase associated with being "just resolved" is

Diffraction by a grating can be visualized from the geometry in Figure 2-1, which shows a light ray of wavelength λ incident at an angle α and diffracted by a grating (of groove spacing d, also called the pitch) along angles βm. These angles are measured from the grating normal, which is the dashed
