The sensor surface (1) on the same side as the cooling finger (4) has a hollow cylindrical attachment (5) and is attached to the cooling finger by circular, force locking connecting elements in the form of external conically shaped clamping rings (2) and a threaded nut (8) The internal bore of the conical attachment is conical and the attachment of the sensor surface to the cooling finger can be made by a screw cap. The attachment can be internally threaded and the corresp. threaded part externally threaded with an internal cone. USE/ADVANTAGE - Esp. for Split-Stirling type machine for cooling infrared sensors. Has vibration-proof, easily detachable connection between sensor cooling surface and cooling finger and ensures uniform temp. distribution over entire sensor cooling surface.
