In this article, we will discuss the fundamentals of the diffraction grating spectrometer. The operation of the instrument is based upon the textbook equations for the far-field interference
For a diffraction grating spectrometer, the grating is the dispersive element instead of a prism. In very simple form, the primary maxima from a diffraction grating for wavelength are found at
Basically, a spectrometer is an optical system consisting of two lenses/mirrors that produces an image of the input slit on the detector. In between the lenses/mirrors is placed a diffraction grating which
Spectrometers have a wide range of applications and uses. Broadly speaking, an optical spectrometer consists of an entrance slit, a diffraction grating or prism, a detector, and routing optics.
The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the
