Abstract

A high-resolution, flat-field, plane-grating, f / 10 spectrometer based on the novel design proposed by Gil and Simon [Appl. Opt. 22, 152 (1983)] is demonstrated. The spectrometer design employs off-axis parabolic collimation and camera mirrors in a configuration that eliminates spherical aberrations and minimizes astigmatism, coma, and field curvature in the image plane. In accordance with theoretical analysis, the performance of this spectrometer achieves a high spatial resolution over the large detection area, which is shown to be limited only by the quality of its optics and their proper alignment within the spatial resolution of a 13 μ m × 13 μ m pixelated CCD detector. With a 1500 lines / mm grating in first order, the measured spectral resolving power of λ / Δ λ = 2.5 ( ± 0.5 ) × 10 4 allows the clear resolution of the violet Ar ( I ) doublet at 419.07 and 419.10   nm .
