The tec5USA Stand-Off Raman Probes are fitted with the highest quality optical filters to suppress any unwanted laser and have focal lengths from 50 mm up to 3 m.

These probes are designed to work seamlessly with the ISI range of HES spectrometers with etendue characteristics to match and designed to minimize unwanted background light. This allows for maximum light collection even at distance. Our Stand-Off Raman probe can be fitted to a robotic arm for deployment by ROV, ideal for remote sensing in hazardous environments.

Our Raman probe is currently being used in the nuclear decommissioning sector to remove the human element from the detection of substances in gloveboxes.

The specifications given below are for the standard RP1000, but the unit is customizable to operate between 500 mm and 1500 mm standoff distances and may be adapted to operate at alternative Raman excitation wavelengths.
