Video camera systems using reflective targets for measuring the flux distribution of concentrated solar radiation became quite common. Here the reflecting targets must have nearly Lambertian reflection properties. Within the frame of the development of a new flux measurement principle using a camera and a target the optical properties of three reflecting and one transmitting target have been investigated. The measurement technique and the results are presented and discussed.
