Unique Technology Unique Technology Unique Technology

The miniRaman Pro builds on Lightnovo’s patented miniaturized Raman technology, combining compact design with advanced optical performance and high measurement stability.

At the core of the system is a patented optical architecture with an integrated reference channel, enabling accurate wavenumber calibration and correction of laser wavelength drift. This ensures that Raman spectra remain stable, reliable, and reproducible over time, even under changing environmental conditions.

The miniRaman Pro further enhances performance through improved laser quality and temperature stabilization, delivering highly accurate Raman shift calibration and excellent spectral stability. This makes the system well suited for both material identification and precise quantitative measurements.

Thanks to its optimized optical design, the miniRaman Pro achieves exceptional sensitivity in a compact form factor, offering performance comparable to systems using deep-cooled CCD detection—without the size, complexity, or operational limitations of traditional laboratory instruments.
