Query: Development of the Fabry-Perot interferometers for the HIRMES
  spectrometer on SOFIA   HIRMES is a far-infrared spectrometer that was chosen as the third generation
instrument for NASA's SOFIA airborne observatory. HIRMES promises background
limited performance in four modes that cover the wavelength range between 25
and 122 $\mu$m. The high-spectral resolution ($R \approx 10^5$) mode is matched
to achieve maximum sensitivity on velocity-resolved lines to study the
evolution of protoplanetary disks. The mid-resolution ($R \approx 12, 000$)
mode is suitable for high sensitivity imaging of galactic star formation
regions in, for example, the several far-infrared fine structure lines. The
low-resolution ($R \approx 2000$) imaging mode is optimized for spectroscopic
mapping of far-infrared fine structure lines from nearby galaxies, while the
low resolution ($R \approx 600$) grating spectrometer mode is optimized for
detecting dust and ice features in protostellar and protoplanetary disks.
Several Transition Edge Sensed (TES) bolometer arrays will provide background
limited sensitivity in each of these modes. To optimize performance in the
various instrument modes, HIRMES employs eight unique fully-tunable cryogenic
Fabry-Perot Interferometers (FPIs) and a grating spectrometer. Here we present
the design requirements and the mechanical and optical characteristics and
performance of these tunable FPI as well as the control electronics that sets
the mirror separation and allows scanning of the FPIs.
