RG Raman microscope
With the RG Raman microscope Lightnovo provides an answer to demanding requirements for Raman spectroscopy. Different laser sources allow measurements at 405, 532, 633 or 785 nm.
The modular design consists of the microscope and one of the spectrometers from the RG or miniRaman series in order to adapt laser wavelength, measurement range or precision to individual requirements. In addition, Lightnovo promises operation in both upright and inverted setups.
The Miraspec software (Windows 7, 10) is connected via USB cable and allows not only data acquisition and operation of the microscope, but also the evaluation of the data, standard evaluations (background correction, peak mapping, peak areas), the creation of a peak database and a chemical evaluation of Raman maps via PCA, MCR and NNLS.
