Raman spectrometer IndiGo Raman-532 nm
Like all of GoyaLab’s IndiGo products, the Raman-532 is an extremely compact spectrometer. It combines an IndiGo spectrometer with increased resolution with a Raman module, including laser, sample holder and protection function to protect from the laser radiation inside.
Due to the longer built-in diffractive optics, the IndiGo HR achieves a resolution of 0.2 nm, resp. 12 cm-1, the measured wavelength range reaches from 150 to 4000 cm. The laser in the Raman module is a continuous-wave laser with 150 mW and a spectral half-width of 0.1 nm. The detachable sample holder can be used to measure liquids or solids in a glass container, or you can manually bring samples to the focal point that you want to measure.
The Raman-532 can either operate autonomously with a battery life of up to ten hours, or it can be connected to a tablet or PC via Bluetooth or USB-C cable.
The freely available SpectroLab software, which can be installed on both PC (Windows) and mobile devices (Android), allows the instrument to be controlled, measurements to be performed and also spectra to be analyzed within the software. Currently, an add-on is being developed for this, which will allow the creation of chemical models and databases.
