Applicable for Upstream + Downstream
Portable dual-laser spectrometer
NEEGALA
The NEEGALA system is incredibly versatile and open to a wide range of applications due to the integration of multiple laser lines in a single device that doesn’t require any user manipulation.

NEEGALA
Multi-channel raman device
The system combines flexibility, functionality, and compact design with total control through software and enables data harmonisation across channels. To overcome the drawbacks of single-line portable or modular Raman units, it is composed of high-performance spectrometers and stable diode lasers that can operate in a variety of modes.
No matter how complex the application or analysis the device is to be used for, the user of traditional single-laser line products is limited to a preselected setup. With NEEGALA, which is much more than just a combination of two single-line units, this is not the case. Since multiple laser lines can be integrated into a single device without the need for user intervention, a wide range of applications that were previously only possible with bulky, lab-based research-grade Raman instruments are now possible with this incredibly versatile system. There is less chance of damaging the sample or the device because internal laser adjustment is not necessary.
The safety of operations is unmatched in the industry thanks to the optional use of a single fibre optic probe (NEEGALA probe) that enables the combination of two bilateral laser lines without signal interference and without the need for manual intervention to use either of the laser lines. The high wavelength line is used for higher resolution with a carefully balanced throughput of the spectrometers, whereas the short wavelength line’s wide spectral range provides a sizable spectral range. To ensure a stable operation of the system, the laser power, spectral range, and signal to noise ratio are all carefully balanced between the 2 channels.
