Many programs need to simulate a point source on the ground to test imaging spatial parameters (i.e. focus, point response function, distortion, field of view, etc.). SDL has built numerous cryogenic multi-function and single function collimators to test these imaging parameters.
- Multi-function collimators enable in-situ optical testing of many configurations on a single thermal cycle

Spatial Infrared Imaging Telescope
SPIRIT III was the infrared sensor aboard MDA’s Midcourse Space Experiment (MSX). This long-wave infrared instrumentation package consisted of a high spatial resolution radiometer, a high spectral resolution interferometer-spectrometer, and an extremely high-off-axis-rejection telescope.
Cryogenic Infrared Radiance Instrumentation for Shuttle
CIRRIS-1A’s goal was to obtain simultaneous spectral and spatial measurements of atmospheric emissions, including airglow and auroral phenomenology.
Commercially Hosted Infrared Program
CHIRP was a flight demonstration program to provide risk reduction for the United States Air Force (USAF) Third Generation Infrared Surveillance (3GIRS) system.
Wide-field Infrared Survey Explorer
The WISE cryogenically-cooled infrared telescope provided a complete stellar infrared map more than 1,000 times more detailed than previous surveys.
