ABSTRACT:
The invention relates to a condenser lens system for microscopes for uniformly illuminating an object field of a microscope objective. The condenser lens system is constituted of at least two individual condenser lenses in a common lens mount, said two lenses having an optical axis each which intersect in a common interspace included by the individual lens members in spaced relation. The point of intersection of the condenser lens system is the point of rotating the entire system to insert the individual condenser lenses required into an illumination beam.
