SOC 600 Handheld Bidirectional Reflectance Reflectometer

The SOC 600 is a portable Bidirectional Reflectance Measurement Device. Using a patented angular imaging technique the instrument fully maps the scattering from a half-hemisphere above the surface to deliver more than 30,000 angularly resolved points in just a few minutes. Beam incidence elevation is variable from, θi = 0° to 85°, while scattering is measured to nearly 90° off normal.The applied imaging technology allows for unmatched speed in generating BRDF data (Bidirectional Reflectance Distribution Function). The small size and ruggedness of the SOC 600 make it possible to perform sophisticated measurements directly on the sample in the field. The instrument currently measures BRDF in the 3-5 and 8-12 µm regions of the spectrum. A visible version of the instrument with three-channel RGB measurement is coming soon.

Novel Angular Imaging Technique

Instead of the time and labor intensive process a goniometric approach to measuring BRDF requires, the SOC600 uses a novel hemispherical mirror and imaging technique to capture the BRDF of a surface. Using a collimated source, the SOC600 maps the recorded BRDF 'image' (shown at right) into a polar coordinate system for incident angles ranging from normal to 85°.

Using BRDF data, other optical properties such as: Directional Reflectance (DR), Hemispherical Directional Reflectance (HDR), Diffuse Reflectance, Specular Reflectance, Specular Lobe, Directional Emissivity (derived from DR at near-grazing angles) are easily derived.
