Mini Pro can generate mapping spectra of fluorescence and Raman by focusing the laser on the sample and collecting the emitted light (fluorescence or Raman) using a spectrometer. Automatic focusing can be achieved in the Z direction. The analysis software can quickly determine the peak energy and intensity of each spectrum. Obtain Mapping images with excellent resolution and contrast. Modular design enables researchers to quickly change wavelength ranges and experimental settings. The system can also be easily configured to obtain polarization spectra and reflectance spectra. It can also be combined with the probe station source table for photocurrent related testing
