The Omni-Diff™ diffuse reflectance probe interfaces to virtually any spectrometer via fiber optics. This compact accessory is equipped with input and output SMA connectors that readily attached to a fiber optic coupler, like the Harrick FiberMate2. It is ideal for diffuse reflectance analysis of samples up to 1.5 meters away from the spectrometer. The Omni-Diff™ measures the radiation diffusely reflected from the sample, deflecting the specular component away from the collection optics. A selection of fiber optics is available for use in the UV-Vis, NIR and mid-IR, as well as a digital imaging system for photographic documentation of the sample. The Omni-Diff™ is ideal for examining neat powders in addition to rough surfaced solids which are too large to fit into the spectrometer.
