Raman spectroscopy uses scattering of laser light to probe molecular structure. The system begins with an excitation laser, routed to the sample via a probe. Signal from the probe is measured by a spectrometer. Also included are software and a sample holder for cuvettes, probes or SERS substrates, and safety glasses. Raman systems come with 532 nm, 638 nm, 785 nm, 830 nm and 1064 nm excitation laser options. In addition, SERS nanoparticle substrates can be used to amplify weak Raman signals for trace level analyte detection.

• Portable: Small footprint, light weight, fiber optic-based spectrometer.
• Sensitive: High quantum efficiency optical design.
• Powerful: Signal-to-noise ratio of >1000:1 (single acquisition).
• Stable: Cooled detector allows low light detection and extremely long integration times.
