Device for the detection of electromagnetic waves and, in particular, of infrared radiation

摘要

A device is provided for the detection of infrared radiation which operates at low temperature. The device contains a detection unit and a cryostat equipped with a cold finger to exchange heat with a cold source. Included is a cold plane having at least one machined portion, each portion having a recess toward the center of the cold plane in the region of a through-slot opening outside the cold finger. A connection element is positioned by insertion into each recess, and is electrically connected to the connector of the cryostat.
