Abstract

According to DIN 67520 a distance of 10 m between sample on the one side and light source or photoreceiver on the other side has to be observed when carrying out reflection measurements. By using a corrected lens it is in principle possible to reduce this distance of the widths of angles given. Various possibilities are examined to separate the path of illuminating rays from the path of rays to be measured.
