Tender Details

Nrl requires a research, test and evaluation scan mirror assembly for use in a laboratory setting (vacuum chamber). The ultimate goal of the scan mirrors will be for use in space-flight instrumentation and hence they must operate in a low earth orbit environment.
Angular scan range: as shown below, the scan angle ranges from 22-68 from horizontal. This scans the field-of-view through +/-46 for 92 field-of-regard (1 margin at each end).
Maximum scan rate: 25 s-1
angular resolution: 0.05, 0.1 minimum
mirror size: 95 mm x 50 mm (scan axis is parallel to the 50 mm side)
we desire the mirror mechanism and electronics to fit into a 1u cubesat form factor. The deployable sunshade is not to be bid upon. The system is designed to be a push-broom scanner which scans back and forth cross-track beneath the satellite. The electronics should be at least class-d with care taken to minimize outgassing materials. The scan mirror should be coated with magnesium fluoride over aluminum coating (acton research ar-1200 or similar coating preferred).
