Abstract:

The Czerny-Turner collimating system used in the Aerospace lamellar grating interferometer is shown to lead to significant instrumental line broadening. This system is compared with an off-axis parabolic mirror system, and the following conclusions are reached. 1 The instrumental line broadening of the parabolic mirror system will be an order of magnitude smaller than for the Czerny-Turner system. 2 The coma of the parabolic mirror system is negligible. 3 The wavefront distortion of the parabolic mirror system is less than that of the Czerny-Turner system.
