The Ocean Optics (Dunedin, FL) Diffuse Reflectance Probe (DR-Probe) measures 45° diffuse reflectance, enhancing UV-Vis and NIR spectroscopy results. The DR-Probe integrates a light source and collection optics into one unit. With the probe’s collection optics fixed in place relative to the light source, the measurement geometry is constant. An included standoff accessory ensures a consistent 40 mm focal length between the probe and the sample. The DR-Probe has rugged, all-metal construction for durability, and its 6W tungsten halogen bulb has a 10,000-hour lifetime.
