  • The ATR2100 portable Raman spectrometer is a new generation of high-performance detection equipment developed by Optosky, integrating ultra-high resolution and portability. This instrument adopts a cooled high-sensitivity CCD detector and a low-stray light optical path design, achieving a spectral resolution better than 6 cm⁻¹ and significantly improving the signal-to-noise ratio. It supports optional excitation wavelengths such as 638 nm and 785 nm, and is equipped with an easily detachable fiber optic probe. With its lightweight body (≤2 kg, 21×21×10 cm³), USB 2.0 data interface, and 5V DC power supply design, it perfectly meets the needs of both laboratory and field testing.
  • The ATR2100 comes with professional PC-based intelligent analysis software, integrating data acquisition, processing, and analysis. It offers multiple measurement modes, including single acquisition and continuous acquisition, to meet the requirements of various application scenarios. The software features advanced functions such as automatic peak finding and baseline correction, and includes a rich built-in material database for rapid sample composition analysis. It supports exporting data in universal formats such as TXT and CSV and directly generates PDF reports.
  • With its innovative optical design and intelligent operation experience, the ATR2100 redefines the performance standards of portable Raman spectrometers. It delivers stable and reliable test results for both precise laboratory analysis and field testing, making it an ideal choice for researchers and industrial inspection personnel.
