THERMAL WINDOW AND METHOD OF FITMENT THEREOF

摘要

A thermal window for fitment over an aperture (4) in a casing for an electronic system comprising a window frame (8) having a recessed face to receive a thermally transparent window member (6) engageable within the recess such that it lies generally flush with the face of the frame (8) at least at an edge portion thereof, and a double-sided self-adhesive frame (9) mount configured to fit over the first face of the frame (8) and the edge portion of the window (6) so that its second adhesive surface presents a forward face by which the window assembly can be engaged over the aperture (4). In particular, the self-adhesive frame (9) mount is a self-adhesive frame gasket (9) serving to effect a gas tight seal at the aperture (4). A window (6) so mounted and a method of mounting such a window are also described.
