InPhotote - Portable Raman System for Rapid Chemical ID
The ability to rapidly identify chemicals on-site is more important now than ever before. The InPhotote is a powerful tool for law enforcement, civil defense, military personnel, or anyone who may encounter suspicious liquid and solid substances. Unlike other technologies, the InPhotote is able to interrogate samples through transparent and semi-transparent containers, keeping personnel and instrumentation away from possible threats. Only the fiber optic probe needs to be close to the sample and analysis is completely nondestructive.
The InPhotote comprises a high-quality Raman spectroscopy system in a rugged, portable package. A frequency-stabilized laser, spectrograph, and TE-cooled CCD detector are integrated into the case. Setup time is minimal, and measurement is simple with the RamanProbe. Optical components can withstand elevated ambient temperatures and are shock-mounted for routine shipping and use.
Most samples can be measured through packaging materials (i.e. glass and plastic) with the RamanProbe. The probe is compact and lightweight for hand-held use, and can be mounted onto remote-controlled vehicles to identify potentially hazardous materials at a safe distance. Probe extension cables (up to 200 m) can be used to extend the samping reach of the unit.
The InPhotote is capable of identifying chemicals regardless of form (e.g. solids, liquids, slurries). Wet samples or water-based solutions do not pose additional identification difficulties.
