A monochromator can use either the phenomenon of optical dispersion in a prism, or that of diffraction using a diffraction grating, to spatially separate the colors of light.It usually has a mechanism for directing the selected color to an exit slit. Usually the grating or the prism is used in a reflective mode.
An echelle grating (from French echelle, meaning “ladder”) is a type of diffraction grating characterised by a relatively low groove density, but a groove shape which is optimized for use at high incidence angles and therefore in high diffraction orders.Higher diffraction orders allow for increased dispersion (spacing) of spectral features at the detector, enabling increased differentiation

In optics, a diffraction grating is an optical component with a regular pattern, which splits and diffracts light into several beams travelling in different directions. 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.
Diffraction by a grating can be visualized from the geometry in Figure 2-1, which shows a light ray of wavelength lincident at an angle aand diffracted by a grating (of groove spacing; groove spacing d) along angles b m. These angles are measured from the grating normal, which is the dashed line perpendicular to the grating surface at its center.
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light’s intensity but could also, for instance, be the polarization state.
Geometry of diffraction, for planar wavefronts. Two parallel rays, labeled 1 and 2, are incident on the grating one groove spacing d apart and are in phase with each other at wavefront A.
As NIR is considered to be a very interesting spectral range for mobile applications, a miniaturized scanning grating spectrometer for the near-infrared has been developed. Palmer C.

The Physics of LASERs, Teacher Edition 3 Teacher Introduction Summary for all Lessons These lessons were written to celebrate the 50th birthday of the LASER. The first working LASER was created on May 17, 1960. This set of three laser lessons introduces students to the properties of lasers, the fundamental components of a laser, and
Designed for operation from 8 to 125 nm (10 to 150 eV), the OP-XCT operates as a monochromator or imaging spectrograph. With a coarse diffraction grating and CCD, it surveys broad extreme UV wavelength swaths, dispersing from 10 to 140 nm on a detector 12 mm wide.
