Dual Wavelength and Industrial Process Raman Probes

Ocean Optics offers advanced Raman probes designed to meet the demands of both research and industrial environments. Our Dual Wavelength Raman Probe features a colinear optical design and high-throughput optics for efficient, simultaneous measurements at 532/785 nm—ideal for complex sample interrogation. The 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.
