Grating direction
WebThe Grating Equation The equation that dictates the diffraction properties of a grating is given by: nλ = d (sin i + sin i’) n = the order of diffraction λ = wavelength of light d = … WebThe grating lines possess a triangular, sawtooth-shaped cross section, forming a step structure. The steps are tilted at the so-called blaze angle with respect to the grating surface. Accordingly, the angle between step normal and grating normal is . The blaze angle is optimized to maximize efficiency for the wavelength of the used light.
