  • Apparatuses for automatic focusing of lens systems, in particular microscopes and instruments for the electronic acquisition of microscope images
    Patent number: 4745271
    Abstract: An improved apparatus for automatic focusing of a lens system, including a space dissector (17) for analyzing the space frequency components of the image planes close to the ideal focus plane, and devices (53, 57) for detecting the position of the plane at which the maximum of space frequencies occurs, close to the ideal focus plane. An electronic device is provided for obtaining a suitable signal from said space dissector (17), to provide an adjustment control signal actuating a servo-control unit controlling the lens focusing, and for thus leading to the image plane having the maximum of high frequency components being placed in coincidence with the ideal focus plane.
