In a projection system, CAD-PRO laser projectors generate the visible lines on the surface of objects or tools. For providing data you may use the PRO-SOFT projection software or access via API. The system is controlled and handled by a PC and remote controls. Installation is done according to customer's needs, including mechanical (ceiling supports, jigs ...) and electrical (turn-key cabinet, distribution boxes, cable ...) components. 

SPECIAL FEATURES

  • SMALL SIZE, LIGHT WEIGHT
    LAP CAD-PRO is the smallest and lightest laser projector in the market. This makes CAD-PRO easy to handle, from installation to replacement and shipping. The projector clicks into its tilting bracket and is fixed with one Allen screw. Only ONE cable has to be connected.
  • MULTICOLOR PROJECTION
    LAP CAD-PRO is the only projector in the market that can simultaneously project in three colors. You may display lines in any shape: outlines, straight lines or curves, icons or text.
  • ENHANCED SERVICE LIFE WITH DIODE LASER SOURCES
    The new CAD-PRO LD models use green laser diodes that offer an operating lifetime of up to 30,000 hours - more than three times the service life of DPSS lasers.
  • DIGITAL CONTROL OF GALVANOMETERS
    The actuators for the turning mirrors in CAD-PRO laser projectors are controlled digitally. This eliminates typical errors of analog systems like thermal drift or susceptibility to EMP. Using the parameters of the digital control, the projectors may be optimized for their individual task.

HOW DOES IT WORK?

LAP CAD-PRO laser projectors contain one or two laser sources, some mirrors and prisms, two galvanometers with axes perpendicular to each other, a cooling system and the mechanics and electronics to house and handle all this.

The laser sources produce a laser spot, that is focused and directed to the first galvanometer mirror. The oscillating direction of the galvanometer defines the first axis of the projection area. If you use one laser source only - either red or green - you get the respective color. If you superimpose both beams you get a yellow spot.

Close to the first mirror the laser spot hits the second, slightly larger mirror. It adds the second axis to the movement of the spot by deviating it in the perpendicular direction to the first galvanometer.

If you move the spot along a series of defined positions in a line or curve, you can see an outline. The movement of the laser spot just has to be fast enough to produce an image that the human eye perceives as a line or curve. This means around 25 cycles, depending on ambient illumination.

As the laser beam can't stop or end in mid-air, you need a surface to watch the projection. If this surface doesn't have the exact shape or position that is given in the CAD data, the projection can be 100% precise but will still be at the wrong position. Exact calibration, reliable CAD data and surfaces or tools that exactly match the CAD data are the fundament of each projection task.
