 Request for information
The RFP-480 Raman probe has been developed for use under the most extreme of chemical conditions.
The patented principle of window adaptation ensures that the probe is constantly stable and virtually maintenance-free. This is achieved by completely isolating all the fibers and optics in the probe tip. The fused sapphire window is protected by the stainless steel alloy, Hastelloy C-276, which is almost temperature- and shock resistant. The RFP-430 Raman sensor can be connected to a laser and to a Raman spectrometer via standard fiber optic connectors. Two different fiberglass bundles with 19 and 7 individual fibers are available. The fiber leading to the laser has a core diameter of 100 µm.
Please contact our application scientists to find out the optimal system configuration to suit your requirements.
