ATR3110-1064 High-Sensitivity Portable Raman Spectrometer
Product Introduction
The ATR3110-1064 High-Sensitivity Portable Raman Spectrometer is a compact, laboratory-grade 1064 nm Raman spectrometer designed for high-sensitivity Raman spectroscopy in scientific research and demanding analytical applications.
The system combines 1064 nm laser excitation, high-extinction-ratio Raman filters, a cooled high-sensitivity InGaAs array detector, low stray light, and high dynamic range to deliver reliable Raman measurements. The 1064 nm excitation wavelength significantly reduces fluorescence interference, making the ATR3110-1064 particularly suitable for high-fluorescence samples such as dyes, printing inks, petroleum products, and biological materials.
With a Raman spectral range of 200–2600 cm⁻¹, spectral resolution of 13 cm⁻¹, and signal-to-noise ratio above 3000:1, the ATR3110-1064 provides laboratory-level Raman analysis in a compact portable platform.

Key Features
• 1064 nm excitation effectively suppresses fluorescence interference.
• High-sensitivity 512-pixel InGaAs detector for improved weak Raman signal detection.
• Detector cooling to -10°C improves signal stability and sensitivity.
• High dynamic range of 80,000:1 supports analysis of samples with strong signal variation.
• Wide Raman range: 200–2600 cm⁻¹.
• Low stray light improves spectral quality and measurement reliability.
• High signal-to-noise ratio: >3000:1.
• High-extinction-ratio Raman filter: OD >8.
• Compact and portable: 30 × 22.5 × 13.2 cm and approximately 7 kg.
• Low power and reliable operation for laboratory and on-site Raman analysis.
• Flexible integration: USB 2.0 communication and multifunctional spectral analysis software.
• Suitable for biochemical analysis, food safety, pharmaceutical research, petroleum analysis, and scientific research.

Working Principle
The ATR3110-1064 uses a 1064 nm laser to illuminate the sample through the Raman probe. When the laser interacts with molecules in the sample, most incident photons undergo elastic Rayleigh scattering, while a small fraction undergoes inelastic Raman scattering.
The Raman-shifted light is collected by the optical probe and passes through the high-extinction-ratio Raman filter assembly, which strongly suppresses the laser and stray-light background. The filtered Raman signal enters the spectrometer and is dispersed by the optical system before being detected by the cooled 512-pixel InGaAs array detector.
The resulting spectral signal is converted into Raman shift information and analyzed by the instrument software. The use of 1064 nm excitation significantly reduces fluorescence compared with shorter-wavelength excitation, improving Raman measurement quality for strongly fluorescent samples.
