Raman spectroscopy is especially useful for reaction monitoring, product identification, remote sensing, and the characterization of highly scattering particulate matter in aqueous solutions. Based on the principle discovered by Prof. Chandrasekhara Venkata Raman, it measures the result of the inelastic scattering of photons.

The AvaSpec-HERO is integrated into the AvaRaman system. Because of the low dark noise of the HERO (only 2 counts), you’ll have a great performance. The superior signal-to-noise ratio (800:1) is important when you’re dealing with small signals, which is typically the case in Raman. Also when small process changes need to be monitored in time, the HERO is superior as the small change process will lead to a small change in signal which can be discriminated by the excellent SN ratio. The high NA optical bench results in a better sensitivity. This will lead to more photons impinging on the detector. Temperature control is very important in Raman measurements to create stable results in time.

Cooling to -10 °C for the lowest noise performance and very stable cooling control ( +-0.1 °C accuracy) is delivering accurate and reproducible results. 
Combined, this provides you with a combination that is suitable for the more demanding applications (low light, better signal-to-noise, low noise ratio). 

The AvaRaman system is equipped with a cooling system. Cooling the detector down to -35°C cooling versus ambient, reduces the noise figures by a factor of 2-3, enabling the usage of longer integration times to enhance the detection of small signals. The AvaRaman system is delivered with special AvaSoft-Raman software. Complementary 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 section on this website.
