THOR
Thermal and Optical Research Chamber
SDL’s THOR facility is used for thermal vacuum environmental
testing and space simulation. The THOR chamber is 12' long and 8' in diameter
and operates as a class-1000 or better clean facility. The 12' x 7' working
volume can be expanded to accommodate a variety of sensor sizes and includes
a 4' x 10' optical bench. The common rigid frame supports ancillary devices
such as scene target generators, black bodies and calibration instruments. The
THOR chamber’s temperature range is -200 C to +100 C. The chamber offers
multiple independent targets, 10 ASA connector ports, two fields of regard,
and has a base pressure of 10-6 to 10-7 Torr.
The THOR facility provides precise absolute radiometry and microradian-level
characterization for optical payloads, scenario-driven evaluation of onboard
processing, thermal balance of assembled payloads, and emulation of spacecraft
jitter. Two smaller-scale thermal vacuum chambers are also available for vacuum
bakeouts, thermal cycling and space simulation.
