Microscope with a proximity sensor |
摘要 |
A microscope with a viewing tube for visual observation of a specimen by an observer, with a control circuit for controlling electrical and/or electro-motor-driven microscope functions, and an illuminating device for illuminating the specimen to be observed is described. The control circuit is connected to a proximity sensor installed on the microscope, which responds to the presence of the observer to the viewing tube. The control circuit includes an adjustable time-delay logic element located in the control circuit for delaying switches of the microscope functions such that the microscope functions are switched after the observer is absent for a predetermined time period.
