On concave gratings for optical purposes
WebConcave Gratings Mono- & Polychromator gratingsOne element – two benefits Mono- & polychromator gratings combine dispersive and imaging properties in a single element. This reduces stray light, which when combined with image correction, optimizes spectrometer performance and the signal-to-noise ratio (SNL). Webstant and straight grooves. Although the concave grating was first introduced by Rowland as early as 1882 [9], only a few studies on the calculation of its diffraction efficiency were reported. One reason is that grooves of a concave grating are distributed on a concave substrate, wherein the Fraunhofer dif-fraction equation cannot be used.
