Paper Abstract

The optical design for an IR imaging spatial heterodyne spectrometer is described. The evolution of the design from a paraxial layout to a final working system is detailed, showing how the basic ideas outlined by the inventors of the ISHS concept were realized in an instrument operating in the long wave IR. Several design constraints unique to operation in the LWIR posed challenges to the design; the choices made to solve these problems are discussed. The predicted imaging performance of the design is modeled, and improvements to the design of a second generation instrument are proposed.
