Abstract

The authors have obtained a quadratic form of the optical path function for a one-dimensional concave grating using the method of least squares, and have derived a corrected Rowland circle. It is not a circle but is very close to a circle. A property of the corrected Rowland circle is examined by means of ray tracing.
