Abstract

We present the design for the multiband imaging photometer for SIRTF (MIPS). MIPS is a versatile instrument that provides diffraction-limited imaging at 30 micrometers , 70 micrometers , and 160 micrometers . MIPS also provides low resolution (5%) spectroscopy in the 50 - 100 micrometers wavelength range to allow the determination of far-infrared spectral energy distributions. The 70 micrometers array can also be used in a special high resolution mode that supports image reconstruction techniques for improved angular resolution. The one cryogenic mechanism on MIPS is a scanning mirror based on a space-qualified design used on the Infrared Space Observatory. We describe modifications to the scan mechanism to optimize it for use at very long wavelengths.
