WebbThere are three major bands that are worked with when optical systems are used within the Earth’s atmosphere. They are the short-wave infrared (SWIR) or near-infrared (NIR), which covers from 0.75 to 3 μm; the mid-wave (MW) infrared, which covers from 3 to 5 μm; and the long-wave infrared, which covers 8 to 14 μm. WebbWe designed, fabricated and tested an engineering model Integrated Dewar Cooler Assembly (IDCA) intended for use inspace instruments. The IDCA incorporated and integrated key four components; the dewar, focal plane, pulse tube coldfinger and long life flexure bearing compressor. The dewar assembly, manufactured by TEMO Corporation. 1
