WebApr 11, 2024 · Diffraction Grating Applications. Diffraction gratings have a number of applications, the most common of which is in monochromators and spectrometers. Monochromators are used to select a narrow band of light from a much wider range of available wavelengths at the source. A common variety of these devices, known as a … WebA blazed grating is one in which the grooves of the diffraction grating are controlled to form right triangles with a “blaze angle, ω,” as shown in Fig. 5. However, apex angles up … WebMeanwhile, the combined output array and the diffraction grating must locate on the conjugate focal plane of the Fourier lens. Grating is aligned in a first-order Littrow configuration at an angle of 30° (corresponding to a wavelength of 1064 nm) in the dispersive plane. ...
