On concave gratings for optical purposes
WebThe theory of the holographic grating is applied to the design of aberration-corrected holographic concave gratings for use with Seya–Namioka monochromators. A method of determining the proper recording parameters is described. The performance of gratings that would be produced by use of the proper recording parameters is evaluated in terms of …

WebThe meaning of CONCAVE GRATING is a reflection grating ruled on a concave mirror. 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.
