Abstract
A device which scans in a raster mode, in particular to a raster microscope, provides a rapid and inexpensive compensation of the disturbing effects of mechanical vibrations on the scanning process. The device includes a sensor for sensing mechanical vibrations and driving a filter whose output, together with the output of the device for the production of a z-signal, is connected to an adder, the output of which drives the device for changing the distance between the specimen and the sensor.
