Abstract
A radiation thermometer assembly comprises a housing to a front end of which is movably mounted an objective lens housing. An eye piece is mounted to the radiation thermometer housing and is arranged to receive light passing through the objective lens. A control system causes relative movement between the objective lens housing and the radiation thermometer housing, the control system being connected to a manual control member for operating the control system. The control member is mounted to the radiation thermometer housing at a position spaced from the objective lens housing.
