Abstract
The present disclosure relates to a surveying instrument including a chassis, an optical system having an optical axis, a stage attached to the chassis and an optical component. The optical system may be adapted to receive and/or transmit light. The optical component is located at, or in proximity to, the optical axis. The received and/or transmitted light passes through the optical component. The stage includes an actuating member arranged to act on the optical component for movement thereof. The actuating member may be responsive to temperature so as to induce a displacement of the optical component relative to the chassis along the optical axis in response to a temperature change.
