Abstract

The invention relates to a method for calibrating an optical instrument which comprises at least a motorized zoom system, an objective, an image sensor and an image processing unit. The method comprises the following steps: establishing calibration data DZRef of the zoom system with a reference objective and storing these in an internal memory of the zoom system; establishing calibration data DORef of the objective with a reference zoom system and storing these in an internal memory of the objective; reading the internal memories of the zoom system and of the objective and applying a digital-optical correction of an image acquired by an image sensor with the calibration data DZRef and DORef. The invention moreover relates to an optical instrument, in particular a digital microscope, to which the calibration method according to the invention can be applied.
