Optional Extras

  • Water Cooling

    For specialised applications that demand minimal perturbance and vibration, we offer a water cooling solution  utilising a high performance thermo-electric chiller. Should your cooling needs change in the future, the water cooling loop can simply be disconnected from the pedestal and the laser head may be cooled passively.

    This option replaces our standard passive cooling pedestal. 

  • Versatile Software Control

    If you require greater control and monitoring of your laser's parameters, consider our PC control interface. Depending on your requirements, users are able to turn the connected laser on and off, refine output power and monitor performance.

  • Remote Diagnostic Support

    We also offer a remote diagnostics option so our laser engineers can monitor the performance of your laser and make necessary adjustments, without the need for a call-out.
