Webb27 okt. 2010 · When an aperiodically ruled grating is designed for an imaging spectrometer, the optical layout and the ruling parameters are chosen to minimise … WebbOften, the incident illumination is perpendicular to the gratings surface. That is, the incident angle is zero. In this case the grating formulation of Eq. (5) reduces to mλ = dsinθ r (8) which is the diffraction grating equation for normal incidence. 2 Example Problems Problem 1. A grating has 8000 slits ruled across a width of 4 cm. What ...
