RPB-830 is a probe designed for the 830nm Raman spectrometer. The samples of solid, liquid or powder can be measured by combining with 830nm semiconductor laser and fiber optic spectrometer. The optical interference filter of OD8 effectively guarantees the filtering of Rayleigh signal. The compact design makes the Raman probe of 830nm more efficient to achieve Raman spectrum measurement.
