Paper Abstract

An apparatus for measuring angle-dependent transmission and reflection of large (40 cm X 40 cm) samples is presented and details of the optical, mechanical and computer aspects given. The apparatus consists of two fixed light sources, an adjustable sample holder and a movable solar cell as the detector. All angle positions are computer-controlled, using a workstation to achieve automatic measurements. Data-processing steps for large and small samples are presented.
