See the journey from feature description to real application in this concise overview. This video walks through a handheld Raman spectrometer in action — automatic calibration, built-in microscope particle detection, laser safety shut-off, and scanning through brown glass, envelopes, and plastic. We also demonstrate its 13,000+ compound and 3,000+ contraband libraries, multilingual interface, and portable field use. A practical look at real screening workflows for customs, security, and lab teams.
