LASER POSITIONING DEVICE CREATING A MARKING BEAM FOR POSITIONING A SUBJECT OR OBJECT IN THE MEDICAL OR INDUSTRIAL FIELD

摘要

The invention concerns a laser positioning device generating a reference beam for positioning a subject or an object in the medical or industrial field, comprising: A) support and directing means (1, 3) connected to a fixed part (2) (wall, partition, ceiling); B) an optical assembly mounted pivoting on the support and directing means (1, 3) and comprising a laser source (50) formed by an infrared crystal laser and a frequency duplicator (507) to emit a green light, and in the laser source (50) output, means for reflecting the beam (51, 52) and a group of two mirrors (53, 54) series mounted in the beam, the first mirror (53) being semi-reflecting and each mirror (53, 54) in said group being followed by an optical system (57, 58) spreading the beams along two perpendicular fan-shaped directions.
