Ocean Optics offers advanced Raman probes designed to meet the demands of both research and industrial environments. Now their range has been extended with the release of their Dual Wavelength Raman Probe featuring a colinear optical design and high-throughput optics for efficient, simultaneous measurements at 532/785 nm—ideal for complex sample interrogation. Also available is the new Industrial Process Raman Probe is built for rugged applications, with a sealed, swageable lens shaft suitable for immersion, pressure, and vacuum conditions.
Both probes incorporate backscattering optics for high collection efficiency and are compatible with a wide range of sample types including solids, liquids, and gases.
