Abstract: A handheld thermal imager includes a housing defining a cavity. A lens barrel has a first end portion and a second end portion. The lens barrel is at least partially disposed within the cavity. A lens is coupled to the lens barrel first end portion. A resilient buffer member supports the lens barrel within the cavity. A thermal sensor is coupled to the lens barrel second end portion. A processing module receives signals from the thermal sensor. A display is coupled to the processing module for displaying a temperature characteristic of a scene.

Abstract: The invention relates to an electronic display and control device for a geodesic measuring device containing capturing means and representation means for detecting and reproducing a measuring range together with input means for controlling the measuring processes. The radiation beam necessary for said measuring processes is emitted by a radiation source and is influenced in the direction of emission thereof by orientating means such that it can be orientated onto a selected target within the measuring range without the capturing means being displaced. Determining the target and initiating the measuring process occurs by displacing a position mark on a screen. A suitable operating module con be produced by suitably combining the representation means with means for inputting data. Said module can also be used independently from and separately from a measuring device which is connected thereto by communication means.

Abstract: A device includes a zoom lens having a focusing lens the position of which varies according to a zooming operation, a first moving part arranged to mechanically move the focusing lens according to the zooming operation, and a second moving part arranged to move the focusing lens in such a way as to electrically correct any shift of focus that results from the movement of the focusing lens caused by the first moving part.
