Aspheric doublets and precision adjustable fold mirrors for 20 K operation in CLAESA cooled, infrared spectrometer is required to operate in earth orbit. The spectrometer performance requirements are discussed to show how package volume constraints and the stressing environment of cryogenic operation affect the detailed design of spectrometer components such as relay imaging optics and fold mirrors. Design steps are described that were taken to insure that the spectrometer would perform well in orbit, with components that are easily manufactured, readily aligned and stable in operation. This design procedure has produced two components of special interest, fast doublets suitable for use at 20 K over the wavelength band from 3.5 to 12 microns, and fold mirrors that can be adjusted to arc second tolerances.
