Device for illuminating measurement surface has radiation device(s), stop(s) and scattering device(s) in beam path, whereby radiation emitted by radiation sources is directed towards stop

摘要

The illumination device has at least one radiation device (2) with at least two radiation sources (11-13), at least one stop (4) and at least one scattering device (3) arranged in the beam path, whereby the radiation emitted by the radiation sources is directed towards the stop. The number of sources is taken from a group of numbers containing the numbers 3 to 20, 24, 28 and so on. Independent claims are also included for the following an arrangement and method of determining the characteristics of reflective bodies.
