Hudson 785 Non-Contact Raman Probe
Hudson™ 785 Non-Contact Raman Probe
High-performance sampling for quantitative analysis
– Optimized for compatibility with Tornado’s HyperFlux™ PRO Plus
– Robust and versatile for process and lab applications
– Compact and lightweight
For ultimate versatility, speed, and sensitivity, Tornado’s Hudson™ 785 non-contact Raman probes feature a high-performance optical interface which enables even the most demanding process or lab applications. The Hudson™ 785 is optimized for compatibility with Tornado’s HyperFlux™ PRO Plus analyzer, providing efficient delivery of the excitation beam and collection of the Raman-shifted light. Its rugged and robust construction allows for superior representative sampling and measurement reproducibility for a wide range of applications including solids, slurries, powders, and heterogeneous mixtures.
Three different sample optics are available with the Hudson™ probe head: a short-focus 8 mm lens, a long-focus 25 mm lens, and a large-spot non-focusing optic that can measure samples over a range of distances. These optics modules can be easily swapped to optimize the optical sampling for different types of samples and containers.
Raman Lens Non-Contact Probe Design
The probe is designed for a single 105 µm excitation fiber and a single large 300 µm collection fiber, which can be multiplexed such that multiple Hudson™ probes can be connected to a single PRO Plus analyzer. With a stainless steel enclosure and sanitary finish (Ra 15 microinch), Hudson™ is sealed against liquid wipedown/spraydown and airborne particulates, and the probe’s small size permits it to be mounted in constricted spaces. Hudson™ can be used for a wide variety of non-contact scenarios, including measurements through windows, sight glasses, sample containers, or in free space, with both fixed sample positions and variable sample working distances.
