Abstract
The imaging properties of varied line-space diffraction gratings are presented for cases in which the underlying grating substrate is bent to form a weak cylinder. Bending the flat grating substrate affects its imaging in two ways: it provides focal properties due to the non-zero substrate curvature, and it changes the local groove spacing across the surface of the grating. Aberration coefficients for such a grating are derived, and a numerical example is presented.
