Precision SOS laser diode module

Precision Laser Scanning has introduced a custom CW laser diode module designed for Start-Of-Scan (SOS) trigger in high power and ultrafast polygon scan heads. The Precision SOS laser diode module has a 0.7mm spot, removing the need for manual focusing or external focusing optics. The beam is visible red and eye safe which makes for easy scan head alignment. The module is 8mm in diameter and 30mm long. The small size allows integration into a compact polygon scan head.

The SOS laser in high power, ultrafast polygon scan heads is typically used out of plane from the working beam to avoid interference. Using a red SOS laser when the working beam is IR, green or UV makes it possible to filter out interference from the bright working beam. The SOS module does not need an expensive laser diode power supply. It runs off a regulated 5VDC supply and the lifetime is more than 10,000 hours.
