Abstract: A condenser unit for providing directed lighting of an object to be measured positioned in a measured object position, wherein the condenser unit comprises a light source for emitting a light beam and an optical element having a positive refractive power. The condenser unit further comprises at least one attenuation element arranged in a common optical axis with the light source and the optical element, which attenuation element comprises a location-dependent light intensity attenuation effect for the light beam incident on the attenuation element, more particularly wherein the light intensity attenuation effect declines from the optical axis towards an edge of the attenuation element.
