Technological Research on Miniature Dewar Flask Lead Wires for Multiple ElementInfrared Detectors

摘要

The technology of miniature Dewar flask lead wires for multiple element infrareddetectors is the key to manufacturing Dewar flasks. Previous lead wire forms (including metal conducting wires inlaid on cold fingers and lead wires carved on the metallized outer surfaces of cold fingers) each have their own advantages and disadvantages. Based on research of the latter technology, the authors have researched a new kind of lead wire technology which can produce lead wires that are O.2mm wide, spaced at O.2mm intervals, and have an impedance of just one ohm (Omega). Vibration and low-temperature environment experiments have produced ideal results.
