ABSTRACT:
An infra-red radiation detector has a pyroelectric element (10), comprising for example TGS material, supported in spaced relationship over a heatsink body (16) for stabilizing the temperature of the element in operation with the space between opposing faces of the element (10) and body (16) containing a thermally-conductive, non-hardening and non-gaseous gel-like medium (22) such as silicon dielectric gel which thermally couples the element with the body. A small quantity of material such as solder or epoxy may be used to bond the element to the body and fix the spacing therebetween or, alternatively, the element may be supported over and bonded to the body simply by means of the medium (22) itself. Capillary action may conveniently be used to introduce the medium into the space between the element and the body.
