Optimal microscope imaging during surgery due to capacitive sensor Monday 22. April 2013 16: 21 In surgery a perfect view of the surgical field is essential. At this point, the physician is often supported by a surgical microscope. To maintain the field of view of the microscope, stable, a high-precision capacitance sensor is used. The optics of the operating microscope is mounted on tripod long arms. This allows the surgeon the best possible positioning of the microscope and the operating crew freedom of movement. The long boom requires constant correction on the hinges to keep the vision and focus range of the microscope for the physician stable. This is the capacitive measuring system "Capa NCDT 6019"By Micro-Epsilon employed. read more
