HDV Series Dewars
HDV Series
The helium dewars in the HDV line contain a single cryogenic vessel. A vapor cooled radiation shield surrounds the vessel and the cold work surface. All interior dewar surfaces are lined with metal foil to provide additional shielding.

Standard work surface diameters are 3, 5, 8, 10, 12, and 14 inches. Larger sizes, including rectangular extensions, are available upon special request.

Applications
HDV systems are frequently used for mid- and far-infrared detector and camera systems, including bolometers, photo detectors, HgCdTe, and InSb. Applications include materials and electronic component testing.

Features

  • Operating temperature range: 1.8K to 4.2K
  • Vapor cooled radiation shield
  • Multiple layers of shielding foil
  • Designed to customer specifications
