Examples of Custom Cryostats

Infrared Detector Test Dewar
Developed for large format FPAs/SCAs
This system uses a single stage Gifford-McMahon Refrigerator to reach temperatures below 40 Kelvin. The stacked shield design allows for FOV baffles and cold stops to be changed to match f# requirements. A stacked aperture wheel and filter wheel are integrated into the system and controlled with externally mounted stepper motors. Interior polishing, electroless gold coating and light tight interfaces reduce the thermal heat load and background light to the detector making an ideal environment for IR detector operation.
- Light tight mechanical interfaces and cable feedthroughs
- Dual 8-position cryogenic optics wheels
- Modular shield design to accommodate changing f# and array sizes
- Multiple surface coatings used, including Nickel, Gold and Aeroglaze
- System included IRLabs Filter Wheel Controller

Custom He3 System
Developed for scientific research
He3 system using a Pulse Tube Closed Cycle Cooler. Instrument is capable of reaching 350mK with 100mW heat lift. This system is currently being used for Dark Matter research at Texas A&M HIPER Lab.
