Abstract
The collimated optical beam in a grating spectrometer may be
circular or elliptical in cross section, so that different parts of the
beam illuminate different numbers of grooves on the grating. Here
we estimate the consequent loss in spectral resolution relative to that
obtained with a beam that illuminates a fixed number of
grooves. The effect reduces the intrinsic resolving power of the
spectrometer by ∼15%, exclusive of other contributions such as
finite entrance-slit width.
