Our Integrated Dewar Cooler Assemblies (IDCA) are engineered with precision for the critical demands of satellite payload sensor solutions. We design and assemble the dewar module with an infrared focal plane array (FPA) and cryocooler. The dewar provides a vacuum environment so the FPA can be cooled for lab testing. The IDCA units also ensure optimal cooling for the most sensitive components of the payload. This temperature control is crucial for peak performance of sensors, ensuring reliability and functionality. Our IDCA solutions are customizable to accommodate the specific needs of any mission.

Cold Chambers

Gemini's Cold Boxes are advanced cryogenic chambers designed specifically for ground-based testing of optical payloads. These chambers create the environment necessary for simulating payload operating temperatures, allowing for assessment of optical performance prior to launch. This design enables observation and analysis of optical behavior under simulated space conditions, facilitating precise adjustments and validation. Customizable to suit specific mission requirements, our Cold Boxes are indispensable for ensuring the reliability and performance of payload optics.
