miniRaman spectrometer

The miniRaman spectrometer with its dimensions (112 mm x 39 mm x 34 mm) is an extremely handy spectrometer that can be used either in Lightnovo microscopes (miniRaman or RG), your own setups or simply as a handheld spectrometer. Models are available for measurements at laser wavelengths of 660 or 785 nm.
Despite the small size, an additional built-in reference channel allows automatic correction of Raman shift and intensity. This results in continuous calibration of the instrument and enables fast and reliable results.
The Miraspec software is connected to the PC (Windows 7, 10) via USB cable or to the smartphone (Android) via Bluetooth and allows not only operation and data acquisition but also qualitative evaluations (phase identification, creation of databases) or quantitative analyses (calibration of Raman peak height or intensity, PLS calibration, MCR, NNLS).
