What are the advantages of choosing the ATR2500 Miniature handheld Raman spectrometer?

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 high-sensitivity Raman spectrometer with breakthrough characteristics. It has ultra-small and ultra-light, High resolution, high sensitivity, high reliability, etc. 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 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 ATR2500 has been strictly tested by hundreds of scientists around the world and collected their improvement opinions. After nearly a hundred versions of updates, the function is very complete and stable, which is very suitable for the development of Raman research.
