Key Advantages of 1064 nm Raman

• Reduced fluorescence interference
• Improved analysis of colored and organic materials
• Better identification of pharmaceuticals and biological samples
• Enhanced performance for forensic and narcotics analysis
• Improved spectral clarity for difficult samples
• Non-destructive field chemical identification
• Through-container analysis capability
• The fluorescence suppression benefit of 1064 nm excitation is consistently emphasized across leading Raman vendors.

1064 nm vs 785 nm Raman Spectroscopy

While 785 nm Raman systems are widely used for general Raman analysis, 1064 nm excitation is preferred for samples with strong fluorescence backgrounds. Pharmaceutical compounds, dyes, biological materials, polymers, narcotics, and colored substances often produce fluorescence that overwhelms conventional Raman signals. 1064 nm Raman systems significantly reduce this effect, enabling more reliable spectral identification.

When 1064 nm Raman is Preferred

• Highly fluorescent materials
• Pharmaceuticals and APIs
• Biological samples
• Colored polymers and chemicals
• Narcotics and forensic evidence
• Complex organic compounds

How 1064 nm Raman Spectroscopy Works

1064 nm Raman spectroscopy uses near-infrared laser excitation to reduce fluorescence generated by the sample during Raman measurement. The Raman-scattered light is collected and analyzed to produce a molecular fingerprint unique to the material being tested. Because fluorescence intensity generally decreases at longer excitation wavelengths, 1064 nm Raman systems can successfully analyze samples that are difficult or impossible to measure using shorter wavelength Raman excitation.
