Abstract:
The present invention relates to a digital microscope that includes an objective lens for enlarged optical imaging of a sample in an image plane. An image with an optical resolution may be represented in the image plane by means of the objective lens. The microscope also includes an image sensor for converting the image, depicted on the image sensor by the objective lens, into an electrical signal. The image sensor includes a matrix of pixels by means of which a maximum image resolution of the image sensor is determined, which is finer than the optical resolution of the objective lens. The objective lens has a maximum magnification factor of at most 40. The optical resolution of the objective lens is defined as a minimum distance between two structures that are distinguishable in the image. The maximum image resolution of the image sensor is defined by a pixel pitch. A quotient of the minimum distance between two structures that are distinguishable in the image and the pixel pitch defines a scanning factor that is at least 5.
