Abstract
Abstract An improved method for providing electrical connection to a photodetector in a Dewar flask is disclosed. A plurality of conductive paths are formed on the inner flask of the Dewar. Each of the conductive paths extends from the side surface on to the top surface of the inner flask. A photodetector having lead tabs is mounted to the top surface of the inner flask with the lead tabs aligned with the conductive paths. The lead tabs are bonded to the conductive paths to provide electrical connection to the photodetector.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
Photodetector apparatus comprising: photodetector mounting apparatus of the Dewar type having an outer flask and an inner flask having top and side surfaces; a photodetector mounted on the top surface of the inner flask; an electrical conductive path comprising an electrically conductive film extending from the side surface on to the top surface of the inner flask; and an electrical lead tab having a first part attached to the photodetector and a second part projecting from the photodetector and having first and second major surfaces, the second part being attached to the electrical conductive path on the top surface of the inner flask, with the first major surface being essentially parallel to and in electrical contact with a surface of the electrical conductive path.
Claim 2
Dependent Claim
124 words
Photodetector apparatus comprising: photodetector mounting apparatus of the Dewar type having an outer flask and an inner flask having top and side surfaces; a photodetector mounted on the top surface of the inner flask; an electrical conductive path comprising an electrically conductive film extending from the side surface on to the top surface of the inner flask; and an electrical lead tab having a first part attached to the photodetector and a second part projecting from the photodetector and having first and second major surfaces, the second part being attached to the electrical conductive path on the top surface of the inner flask, with the first major surface being essentially parallel to and in electrical contact with a surface of the electrical conductive path.
Claim 3
Dependent Claim
32 words
