(QR200-ANGLE-VIS) 200 µm Premium Reflection Probe, VIS/NIR, 2 m, 30 Degree Window

Ocean OpticsSKU: QR200-ANGLE-VIS


An angled reflection probe works well for reflection and backscattering measurements of powders and dense solutions. It has the same 6-around-1 fiber bundle configuration as our standard reflection probes, but with a 30° angled window at a small distance from the fiber bundle tip. This serves to reduce specular reflection effects when the probe is immersed in powders or dense solutions, and allows the probe to maintain direct contact with those samples for consistent measurements.

Probe design — 6-around-1 fiber bundle design at probe end

Angled window — stand-off window at 30º allows direct contact with powders and solutions

Fiber type — probe comprises Visible-NIR (400-2100 nm) fibers

Core diameters — 200 μm and 400 μm options
