Abstract
A reflectometer, comprising an illuminator in a 45°/0° configuration with a light source formed by a lamp and an illuminator optic. Light emitted by the lamp is passed after reflection via a measuring opening into a housing and supplied to a measuring system contained therein. Furthermore, the illuminator optic is formed by a number of light guides which start at the light source and end in the form of a rim with a conoidal emission side. The light guides form one or several groups, a group of light guides being made in one piece of plastic.
