Device emitting a laser beam mounted in a tube and intended to serve as a level and to carry out sightings and traces.

摘要

The system consists of a calibrated tube (2) inside of which is a diode laser transmitter (1), mounted so that the optical transmission axis coincides with the tube axis. A mirror (8) directs the laser beam in a direction perpendicular to the axis. The tube is rotated around the axis. Inside the tube is a spirit level (5) whose bubble is visible through a window in the tube. The tube also houses an electronic power circuit (4) together with batteries (3). USE/ADVANTAGE - Small size and can be mounted on large range of supports, whilst ensuring best possible precision along vertical and horizontal target lines.
