ABSTRACT:
A pyrometer adapted to be disposed remotely from a heated target employs a manually operated optical range finding device for measuring the distance between the target and the pyrometer. The device includes an objective lens mounted in a rotation-type focusing mechanism, split image effect prisms and a viewing screen. A split image appears on the screen when viewing until the mechanism is rotated to a unique angular position at which the image split disappears, the unique focusing position being a monotonic function of the distance. A mechanical gearing arrangement responsive to mechanism rotation is connected to a multi-turn potentiometer having oppositely disposed fixed contacts at each end and a movable contact. The movable contact is moved along the potentiometer in accordance with rotation of the mechanism. For each unique focusing position of the lens there is a corresponding unique position of the movable contact with respect to the end contacts.
