  • Limit switching apparatus with defined overtravel for specimen protection on microscopes with motorized focusing drive
    Patent number: 5315080
    Abstract: A limit switching apparatus with defined overtravel for specimen-objective protection on microscopes having a motorized focusing drive. A stored focus position or position of the specimen stage can be overtraveled by a fixed amount. The maximum travel path of the specimen stage is additionally limited by a switching rod and a short-circuiting switch, in order to ensure reliable specimen-objective protection even in the event of a fault in the control electronics.
