Reflectance Probe for Measuring Powders and Viscous Liquids

Name: Reflectance Probe for Measuring Powders and Viscous Liquids
SKU: OFFP-0006

Cat No:OFFP-0006

Description

To effectively measure the reflectance of powders and highly absorbing viscous liquids, Avantes has introduced a specially designed reflection probe. Users simply insert the probe into the powder or viscous liquid. Light from the illumination source is coupled into a fiber bundle of six fibers via a standard SMA905 connector, which directly connects to the probe tip and illuminates the sample material through a 45-degree sapphire window. This angle prevents direct reflection from the window, improving the measurement dynamic range.
