摘要
In this paper, we present and analyze an improved spectrometer design that has evolved from studies of the focal properties of transmission gratings in converging light beams. This design uses a variable line space grating at a fixed angle of incidence to focus the diffracted light in one dimension, producing resolutions in excess or 1000 over a large wavelength region. Attractive features of this concept include high throughput, simple wavelength scanning, simple optical elements (plane gratings and plane and toroidal mirrors), and relatively inexpensive realizations. After presenting a mathematical analysis of the primary design features, we discuss implementations of this design both as a spectrometer and as two versions of beamline monochromators. Design parameters for the two monochromators will be given.
