Abstract (en)

[origin: WO2017211584A1] The invention relates to a digital microscope (16; 17), which comprises an objective (11) for the magnified optical imaging of a sample (10) in an image plane. An image can be provided in the image plane with an optical resolution by means of the objective (11). The microscope (16; 17) also comprises an image sensor (12) for converting the image imaged onto the image sensor (12) by the objective (11) into an electrical signal. The image sensor (12) comprises a matrix of pixels, by which a maximum image resolution of the image sensor is determined, which maximum image resolution is finer than the optical resolution of the objective (11). The objective (11) has a maximum magnification factor of at most 40. The optical resolution of the objective (11) is defined as a minimum distance of two structures that can be distinguished in the image. The maximum image resolution of the image sensor (12) is defined by a pixel distance. A quotient of the minimum distance of two structures that can be distinguished in the image and the pixel distance defines a scanning factor, which is at least five.
