miniRaman microscope
Measuring 12 cm x 13 cm x 28 cm, the miniRaman microscope is the world’s smallest confocal Raman microscope and enables measurements at laser wavelengths of 660 or 785 nm.
The modular design consists of the microscope and one of the miniRaman spectrometers to customize the laser wavelength, measurement range, or signal-to-noise ratio to individual requirements. In addition, Lightnovo promises possible operation in both upright and inverted setups.
The Miraspec software (Windows 7, 10) is connected via USB cable and allows data acquisition and operation of the microscope as well as data evaluation, standard evaluations (background correction, peak mapping, peak areas), the creation of a peak database and chemical evaluation of Raman maps via PCA, MCR and NNLS.
