AvaRaman-Supreme

pdf Raman is a precise and versatile measurement tool. It only has one downside: Raman signals are difficult to detect due to the required combination of high resolution with high sensitivity.

The AvaRaman-Supreme series spectrometers solve this problem by offering extremely high sensitivity combined with high resolution. Up to six times the sensitivity of a comparably priced Raman system can be achieved. Measurements can be done faster and more precisely.

By redesigning the optical bench and especially the light entrance, more than 95% of the light coming out of the fiber optic cable reaches the detector. The standard solution with an entrance slit only sees 15 percent of the photons reach the CCD.

AvaRaman-Supreme-TEC series spectrometers have a three-stage Peltier cooling systems, which provides ΔT down to -30°C cooling to ambient for superior dark noise reduction, keeping the detector at a steady 5°C. Thanks to the PID controller, this temperature is stable within a 0.1°C bandwidth. All AvaRaman systems are delivered with special AvaSoft-Raman software. Panorama-Pro software is available for Raman interpretation and functional group assignment.

A selection of different probes is available to select the right one for your application. For more information on our software solutions including AvaSoft-Raman and Panorama-Pro, please refer to the software pages on this site.
