Surface Optics SOC-210 BDR Bidirectional Reflectometer (0.35 to 1.6 micrometer)

Specification

Measurements:

Full hemispherical bi-directional reflectance distribution function (BRDF) measurement with both linearly polarized and unpolarized incident light

Unpolarized BRDF

Linear Polarized BRDF (Linear Mueller Matrix components)

Bidirectional Transmittance Distribution Function (BTDF)

Spectral Range: .35 to 1.6 micrometer wavelength

Angular Coverage - accuracy 0.1º for each:
