Main components:

The generator consists of two parts: control unit and emitter. The emitting element is a laser diode.

Principle of operation:

Control unit provides a constant or pulsed current through a laser diode located in the emitter at the end of the tube attached to a stand with adjustable height. Tube contains lens with an aperture of 18 mm. Distance between lens and laser diode can be adjusted steplessly. Beam can be tuned to divergent, quasi-parallel, or convergent.

Operating conditions:
  • Humidity ≤ 80%
  • Temperature 283 – 308 К
  • Pressure 95 - 105 kPa
