The ATR3100 portable Raman spectrometer uses a cooled high‑sensitivity CCD, a signal‑enhancing optical system, and an ultra‑narrow linewidth laser. Combined with a highly reliable optical design and low‑noise electronics, it delivers an ultra‑high signal‑to‑noise ratio and stable measurement results.

Lightweight and portable, with a built‑in lithium battery, it is suitable for various complex environments and outdoor field applications, making it an ideal choice for research, industrial inspection, and on‑site rapid testing.

01 Product Highlights

Ultra‑High Sensitivity · Accurate Capture of Weak Signals — Uses a Raman‑signal‑enhancing TEC‑cooled CCD; the detector can be cooled to as low as ‑15 °C, effectively reducing dark noise and improving weak‑signal detection capability.
High Signal‑to‑Noise Ratio · More Reliable Detection Results — Combines an ultra‑low‑noise circuit design with a highly reliable optical system to achieve a higher signal‑to‑noise ratio and better spectral quality.
Ultra‑Narrow Linewidth Laser — Laser power up to 600 mW with stable output, meeting the needs of high‑precision Raman analysis in multiple scenarios.
Excellent Low Stray Light Design — Effectively reduces fluorescence interference and improves peak resolution, especially suitable for complex sample detection.
Research‑Grade Performance at an Accessible Price —Benchtop high‑end Raman → high accuracy, but expensive and not mobile; Low‑end portable Raman → mobile, but poor SNR and unreliable data; ATR3100 Breaks This Deadlock

02 Multiple Excitation Wavelengths Available to Meet Different Sample Detection Needs

Different samples have different optimal excitation wavelengths. The ATR3100 supports free configuration of multiple laser wavelengths to precisely match your application scenario.

Suitable for Raman characterization of various materials, easily handling complex samples with fluorescence, dark color, or weak signals.

03 Portable Operation, Quick to Use

Connect the device – Plug in the probe and power on for immediate use
Acquire spectrum – One‑click acquisition for fast results
Spectral analysis – Automatic processing, peak identification
Export results – Data saving and export

Built‑in high‑capacity lithium battery for long endurance, worry‑free outdoor testing
