miniRaman Pro combines two patented optical innovations. Light Compression concentrates the Raman spectrum onto a single CMOS detector row, minimizing detector noise and enabling high sensitivity and SNR without deep cooling. An independent off-axis reference channel simultaneously records an internal polystyrene standard, spatially separated from the sample spectrum to prevent signal overlap. This reference enables automatic Raman-shift and intensity calibration after every acquisition, compensating laser wavelength and power drift. Combined with close-packed optics and a high-efficiency transmission grating, this architecture delivers stable, reproducible, research-grade Raman performance in a compact handheld instrument..
