摘要： The present invention concerns a method for producing a microscopic image with an extended depth of field by means of a microscope. The microscope comprises an images sensor that comprises pixels that are arranged as a matrix that is formed by lines. In a step of the method, a plurality of microscopic frames of a specimen is acquired while a focus position (z) is changed. The microscopic frames are acquired line by line. The focus position (z) is changed over a course of acquiring individuals of the microscopic frames. In a further step, parts of individuals of the acquired lines are identified. These parts sharply image the specimen. The identified parts of the lines are composed in order to form a microscopic image of the specimen with an extended depth of field. Furthermore, the present invention concerns a microscope.

摘要： The invention concerns a functional module (02) for a microscope. That functional module (02) comprises a mechanical interface (11) for removable mounting the functional module (02) to a module support of the microscope. The functional module (02) further comprises an optical interface (12) for establishing an optical path (09) from an objective (03) of the microscope to the functional module (02). Furthermore, the functional module (02) comprises at least one image sensor (21). The functional module (02) comprises a first and a second microelectromechanical optical system (17, 18). The first microelectromechanical optical system (17) is configured for enhancing a depth of field on a first optical subpath (14) that is directed to the image sensor (21). The second microelectromechanical optical system (18) is configured for enhancing a depth of field on a second optical subpath (16) that is directed to the image sensor (21). The invention further concerns a microscope.

摘要： The invention concerns a method for capturing and displaying microscopic images of a sample to be microscopically examined using a digital microscope. In a step, a sequence of microscopic images with enhanced visual information in a third geometric dimension is captured. The sequence of the microscopic images is displayed while it is captured. A visual representation of a capturing range in the third geometric dimension is displayed at a graphical user interface. A user input that defines at least one adjustment of the capturing range is received resulting in an adjusted capturing range. At least one parameter of detecting visual information in the third geometric dimension is adjusted according to the adjusted capturing range. It is continued to capture the sequence of the microscopic images with the enhanced visual information in the third geometric dimension applying the at least one adjusted parameter. Furthermore, the invention concerns a digital microscope.

摘要： The invention relates first to a camera module for a microscope. The camera module comprises an optical interface for inserting the camera module into an imaging beam path of the microscope, which imaging beam path images a nominal intermediate image. Furthermore, the camera module comprises an electronic image converter and a functional element for changing an intermediate image plane, which functional element is arranged in a beam path of the camera module between the optical interface and the image converter. The camera module also comprises a first optical assembly having an optical power, which first optical assembly is arranged in the beam path between the optical interface and the image converter. According to the invention, a distance between the functional element and the optical interface along the beam path or a distance between the first optical assembly and the optical interface along the beam path can be changed. The invention further relates to a method for operating the camera module.
