RG Pro Raman Spectrometer
Flagship research Raman spectrometer of ultra-high accuracy
Lightnovo’s top portable Raman spectrometer series for the most uncompromising research and industrial tasks. The Pro instruments combine high-efficiency transmission diffraction optics at up to 85% throughput, deeply cooled detectors and higher-power lasers — delivering an exceptional signal-to-noise ratio, the highest data stability and record spectral resolution.
Key advantages
Ultra-high spectral resolution
Down to 1.8 cm⁻¹ depending on model and slit configuration — confident separation of closely spaced peaks and analysis of fine crystal structure.
Deep detector cooling
Thermoelectric cooling minimises detector thermal noise — critical for very weak signals and long integration times.
Maximum optical throughput
Up to 85% transmission efficiency gives a signal-to-noise ratio of up to 5000:1 and beyond.
Patented calibration
The built-in reference channel continuously compensates laser drift — absolute wavenumber accuracy measurement after measurement.
Broad spectral range
Covers both the low-frequency region from 70 cm⁻¹ and high-frequency modes up to 3700 cm⁻¹.
