The pRaman is a portable Raman spectroscopy system to be carried out for out-field work. It comes with a flexible optical fiber probe for probing of samples which is not possible to be extracted . The pRaman comes with near-infrared laser (785nm or 830nm) which is preferred for samples with high background fluorescence.

The spectrometer, integrated into the pRaman, comes with a high-sensitive, back-illuminated and low-etalon cooled-CCD linear detector, which is ideal for measuring weak Raman signals.

The compact design along with the flexible fiber probe make it easy for user to bring the system for out-field applications. Not limiting to solid or powder sample, user can use the pRaman to measure liquid samples with an optional liquid sample holder.
