High Sensitivity & High Resolution Portable Raman Spectrometer Feature  Describe: space ATR2500 is a Raman spectrometer developed by Optosky for more than 20 years. After 5 years, it has developed a brand-new, optimized and designed Ultra-high sensitivity detector; Ultra-low noise circuit; high-sensitivity Raman spectrometer with breakthrough characteristics. It has Ultra-light, ultra-small, ultra reliable; Powerful spectral analysis software; Eliminate fluorescent background; Peak search and display; Friendly man-machine interface. ATR2500 adopts Optosky's latest full free space optical path technology, which increases the Raman signal collection efficiency by nearly 4 times, thereby increasing the sensitivity by 4 times. The ATR2500 Raman spectrometer is very suitable for laboratory scientific ultra-small and ultra-light, High resolution, high sensitivity, high reliability, etc. research. It is small in size, high reliability, easy to measure, and the detection results are accurate and reliable. The excellent low stray light design of ATR2500 makes it easy to use. The multi-function software randomly distributed by Research of Research Institute ATR2500 has been strictly tested by hundreds of scientists around the world and collected their improvement opinions. After nearly a hundred versions of updates, Forensic Medicine the function is very complete and stable, which is very suitable for the Material science Medical immunoassay development of Raman research.
