Raman Spectrometers 785nm Raman Systems

785nm Portable Raman spectrometer

DETAIL

Portman-785 is equipped with a fiber spectrometer for Raman spectroscopy detection. It is easy to operate and the results of tests are objective and accurate. Compared with the traditional 785nm Raman spectrometer, the sensitivity of Portman has been greatly improved, it can detect weak Raman signals at the cellular level. It’s definitely a portable Raman spectrometer which can be used for the screening of raw materials, field testing, graphene synthesis reaction, biological medicine, material analysis and identification.
