Abstract
A microscope condenser housing having an annular slit to receive filter slides, which during their insertion are arrested in two defined positions. A locking device effective against the outward motion of the filter slides and additionally locking the filter slides in at least one of the defined positions is provided. Incorrect inverted insertion of the filter slides is also prevented. The locking by the locking device is readily released manually by means of a locking lever projecting from the condenser housing.
