ABSTRACT:
The present invention provides a laser theodolite device and kit for converting a new or pre-existing theodolite into a laser theodolite. More specifically, in one embodiment, the laser theodolite device comprises a theodolite having a visible and/or reflective laser source integrally mounted within the theodolite telescope for generating a laser line along the centerline portion of the telescope line of sight. The kit for assembling a laser theodolite from a new or pre-existing theodolite includes a universally mountable bracket with a laser source secured thereto. The universal bracket is constructed and arranged to be mounted at a forward end of a theodolite telescope housing with the laser source being positioned at about a right angle with respect to the telescope centerline. A mirror mounted at about a forty five degree angle is adjustably positioned in the universal mount to reflect the laser beam produced by a laser source along the centerline portion of the line of sight of the theodolite's telescope lenses. Positioning of the laser beam to coincide with the telescope cross hairs is accomplished via adjustment screws provided on the mounting bracket.
