Abstract
A compact Dewar for imaging systems having multiple detector elements to support multiple imaging systems.
Claims11
A dewar system comprising:
- an evacuated envelope;
- a coldfinger;
- the coldfinger being located within the evacuated envelope, wherein a portion of the coldfinger is maintained at a first cryogenic temperature;
- a first detector assembly;
- the first detector assembly being mounted to the coldfinger and being substantially maintained at about the first cryogenic temperature;
- a second detector assembly;
- a thermal bridge assembly;
- the second detector assembly being mounted to a first location on the thermal bridge assembly;
- the coldfinger being mounted to a second location on the thermal bridge assembly;
- the thermal bridge assembly being configured to substantially provide a difference in temperature between the first location on the thermal bridge and the second location on the thermal bridge assembly;
- the thermal bridge having a thermal resistance configured to provide a predetermined difference in temperature between the first detector assembly located on the coldfinger located on the second location on the thermal bridge assembly and the second detector assembly located on the first location on the thermal bridge assembly.
