Raman spectrometeris is mainly used in scientific research institutes, physics and chemistry laboratories, biological and medical fields and other optical aspects, research material composition determination and confirmation, can also be used in criminal investigation and jewelry industry for drug testing and gem identification. The instrument is known for its simple structure, simple operation, fast and efficient measurement, low-wave measurement capability, and the co-focus optical path design for higher resolution, um-grade micro-zone detection of the sample surface, and this can also be used for microimage measurement.
