CORRECTED CONCENTRIC SPECTROMETER

摘要

A high resolution aberration corrected concentric spectrometer (101) includes a convex diffraction grating (100) having a plurality of nonparallel grooves (102). The grooves (102) of the convex grating (100) provide correction for field aberrations. The utilization of the convex diffraction grating (100) enables the present spectrometer (110) to provide highly accurate spectral imaging with greatly improved resolution. By utilizing the convex diffraction grating (100) having curved nonparallel grooves (102), the spectrometer (110) is functional for a large number of applications.
