Abstract
New developments in interference filter technology utilizing low thermal expansion coefficient materials which are deposited free of voids using variants of ion-assisted- deposition techniques have made possible the development of a new class of low-cost, lightweight remote sensing instruments. These instruments can easily have a throughput two orders of magnitude larger than similar dispersive monochromators in addition to having a stray light rejection somewhere between that of a single and a double monochromator for a bandpass of the order of one nanometer. Results from environmental testing, measurements of stability in space, and unique problems associated with spectral radiance calibrations with these interference filter instruments are described.
