Mini Diff 3D (Hemispheric) Scatterometer BRDF/BTDF
Brochures
Learn about advanced 3D scattered light measurement techniques with the Mini-Diff series of hemispherical scatterometers, designed for accurate BRDF (Bidirectional Reflectance Distribution Function) and BTDF (Bidirectional Transmittance Distribution Function) characterization of reflective and transmissive materials.
In this brochure, we introduce the Mini-Diff V2 portable system and the Mini-Diff VPro laboratory instrument, highlighting their capabilities for fast, stable and precise scattering measurements across multiple incident angles and in RGB and near-infrared wavelengths. We explain the calibration methods, which use black and Lambertian standards to ensure reliable and accurate data, and describe how the results can be exported in versatile formats compatible with optical design software. Additionally, the brochure explores various applications such as automotive reflector and diffuser characterization, photorealistic rendering, display quality control and detailed material analysis of anisotropic and diffusing surfaces.
