Our new, innovative Raman probe design features a modular, user-replaceable tip and fibers, which allows you to reconfigure your sampling optics to each new application. Choose from our standard probe tip, a longer BallProbe® for process, or our unique SM05 adaptor with 12.7 mm lenses to access focal lengths ranging from sub-mm to up to 50 mm from the probe tip. All probes are optimized for use with our f/1.3 Raman spectrometers to maximize collection efficiency and signal.
Our standard probe comes with a 4 cm long, 11 mm working distance probe tip that works well for most Raman applications. This probe can be easily reconfigured at the factory or by the user with one of the probe tips below to adapt to a new application or operating environment. OEMs may also couple directly to the probe body with their own sampling optics or probe barrel. Fibers for routing excitation light from the laser and collected light to the spectrometer are included.

Our standard probes have been used in a wide variety of applications, including identification of plastics. Our new contact ball probe tip has proven ideal as a Raman process probe to monitor fermentation of sugar. It has also been used with ultrasonic capture for in-situ detection of microplastics, as published in Spectroscopy Magazine’s June 2020 special issue on Raman (read it here!).
