Detector Dewars

 
Metal dewars for cooling scientific-grade detectors have been a cornerstone of our business since its inception.  Our products are used to cool infrared, radiation, CCD, and other detectors.  Detectors may be cooled by direct or indirect contact with a cryogen or other mechanical or electric device.
 

Typical Construction

• Aluminum or stainless cryogen reservoir and vacuum shell
• Side-looking or down-looking window configuration
• Multi-layer superinsulation for low radiation losses
• Gettering for long vacuum life
• Low thermally conductivity structures and wiring
• Re-pumpable valve for evacuating vacuum annulus
• Suitable device interface
• Hermetic or ceramic electrical connectors

Options

• Temperature, level, or other sensors
• Cryogen auto- or gravity-fill replenishment systems
• Optical windows, mounts and filter wheels
