Dewar packaging

The Infrared Imaging Systems (IRIS) detector/dewar packaging facility is completely automated and maintained to ISO9001 standards. The flexible manufacturing approach allows simultaneous production of first-, second-, and third-generation modules. The factory is a proven supplier of HgCdTe, InSb, and uncooled products, and has delivered more than 70,000 IR detector/dewar assemblies to date.

The facility has complete environmental test capability and fully supports cryogenic systems integration of J-T cryostats, integrated cryocoolers, and TE coolers. Comprehensive structural and thermal analysis is brought to each job, including examination of FPA stress and thermal stability. Extensive cooler interface expertise and qualified 20-year vacuum life for each unit maintains peak operational performance with long shelf life.

The IRIS standard product philosophy is:

  • Reduced technical risk

            - 70% components standardized

  • Reduced labor cost

            - Identical assembly processes

  • Reduced material cost

             - Moderate component volumes maintained in stock

  • Reduced NRE

             - Automated CAD tools with embedded rules
             - Modularity facilitates optical interface customization
