Abstract

An infra-red radiation detector having a Dewar type vessel is provided with a coupler which is coupled to the wall of the vessel. The coupler includes a fiber which can transmit infra red radiation and which terminates close to a detector provided in the Dewar type vessel. No special optical arrangement is required in order to couple an external fiber to the detector and the arrangement is inherently aligned.
