ASKION LASER-line® Laser cw-Module

  • Galeriebild

The LASER-line® Laser cw-modules are standardized modular. Wavelength, optical power, beam profile and spectral filters can be configured according to the particular requirements.

  • selectable operation mode: „power stabilized“ and “constant current”
  • customized emission spectrum (optional)
  • polarization better than 100:1 over the whole dynamic range (optional)


  • Galeriebild
  • mechanical shutter
  • interlock-function by separate laser power line
  • optical power analog controllable or dimmable
  • many control commands and status information via RS 232
  • digital output „laser OK“ / digital input „laser ON/OFF“
  • integrated life time counter
  • integrated self diagnostic
  • differentiated status display by two LEDs

Configure your Laser cw-Module according to your requirements: wavelength, optical power, polarization ...
