凹放物面回折格子に関する考察 第1報

Abstract

Grating is the excellent dispersive element in spectroscopy. Especially in ultra violet region concave grating is the only instrument because of its dispersion and image formation faculty. In general spherical concave grating is used and the research of its theory had been began by Mack et al, Beutler, and synthesized to perfect form by Namioka. In general image formation concave paraboloid mirror is often used as well as spherical mirror, but it has not been analysed yet the behavior of concave paraboloid grating which was cut grooves on the surface of concave paraboloid mirror. General aberration formura about concave paraboloid grating was calculated by the method of ray-tracing. Comparison with the aberration of spherical grating and mew type of mounting will be studied successively.
