Abstract

The invention relates firstly to a method for determining a mechanical deviation on a displacement path of an optical zoom lens, in particular on a displacement path of an optical zoom lens of a microscope. The optical zoom lens is arranged in a beam path between an object to be recorded and an electronic image sensor. In a first method step, an optical marker is introduced into the beam path at a position of the beam path located between the object to be recorded and the optical zoom lens, such that the optical marker passes the optical zoom lens and then is depicted on an image in whicha position of the optical marker is detected and determined. This is compared with a reference position of the optical marker in order to determine the mechanical deviation on the displacement path of the optical zoom lens. The invention further relates to a method for correction of a displacement error of an image recorded by an electronic image sensor and to an electronic image recording device.
