The Lockheed Martin - University of Arizona Infrared Spectrometer (LAIRS) is designed to image the emission
lines of celestial objects in the 1.3-2.5 μm regime. The Instrument has been built and tested at the Lockheed
Martin Space Systems Advanced Technology Center, and demonstrated to work at cryogenic
temperatures. The Instrument employs a tunable Fabry-Perot Interferometer (FPI) to select the wavelength at
which the Instrument images targets. The FPI employs voice coil actuators and capacitive sensors to maintain
parallelism of its reflective lenses and control their gap spacing. During functional tests of the FPI and the
LAIRS instrument, finesse numbers of 60 and 24 were measured for the interferometer at room temperature
and 80K, respectively. This measurement was performed using a laser operating at 1529.33 nm. This paper
presents an overview of the optical, mechanical, and control design of the FPI, as well as a summary of cryogenic
test results.
