Abstract
An infrared ray detector includes, an infrared ray detection element farbicated in a water which is produced by growing a semiconductor responsive to infrared ray on a high resistance substrate, a metal submount provided with two lead terminals insulated from each other, to which submount the infrared ray detection element is mechanically fixed, an adiabatic vacuum vessel for containing and cooling the infrared ray detection element, to which vessel the metal submount is mechanically fixed, the infrared ray detection element and the metal submount. The metal submount and the adiabatic vacuum vessel are respectively adhered to each other by solder.
Claims10
An infrared detector comprising:
- a semiconductor infrared ray detection element disposed on a high resistivity substrate for generating an electrical signal at a pair of electrical terminals in response to incident infrared rays;
- and
- a metal submount including a metal plate, two electrical lead terminals electrically insulated from each other and from said plate, said plate containing at least one hole for provisionally mounting the submount on a dewar with a fastener passing through the hole, wherein said element is soldered to said plate and the electrical terminals of said element are respectively electrically connected to the lead terminals of said submount.
The infrared ray detector of claim 6 wherein said lead terminals are electrically insulated from said plate by a ceramic material.
The infrared ray detector of claim 6 wherein said infrared ray detector element is soldered to said submount with a low melting point solder.
