RG Raman spectrometer

The RG Raman spectrometers with available laser wavelengths of 405, 532, 633 and 785 nm provide high spectral resolution, high sensitivity and cover a wide spectral range. They use diffraction optics with a very high throughput and a very stable laser power, making them ideal for quantitative measurements or long-term measurements.
The high resolution especially in the low wavenumber range makes them ideal for elucidation of structures, as well as intermolecular processes of organic materials in these low frequency ranges.
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, spectral normalization).
