Duetto 532 Series

Duetto 532 Series achieves impressive single frequency performance with our proprietary BRaMMS Technology®. Whilst many applications can make use of this wavelength, it is particularly well-suited to surface-enhanced Raman spectroscopy.

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. 

  • 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.

    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.
