Materials & Processes

High performance electro-optical sensors require specialized materials and processes that promote or control their targeted structural, thermal, or chemical properties. SDL has developed a versatile portfolio of advanced materials and processes relevant to the fabrication of state-of-the-art sensors and space-based instrumentation.

Experience

WISE

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.

SPIRIT III

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.
