  • Patent number: 11226478
    Abstract: The present invention relates to a method for viewing a specimen using a microscope which comprises an objective lens and an image sensor for converting an image formed on the image sensor by the objective lens. A field of view of the microscope can be varied by selecting a section of the image sensor. In one step of the method, an initial image of at least a partial section of the specimen is captured with the microscope, for which a first field of view is selected on the microscope. The initial image is analyzed to determine at least two differing fields of view forming a partial area image, wherein a partial area of the initial image is formed by each of the fields of view forming a partial area image. Images of the partial areas of the specimen are captured for each of the determined fields of view forming a partial area image. The invention further relates to a microscope for viewing a specimen using a microscope.

  • Publication number: 20190384049
    Abstract: The present invention relates to an image conversion module for a microscope, the image conversion module being designed to convert images using an additional function. Said image conversion module initially comprises at least one functional element for implementing the additional function which is used for recording an extended depth of focus, for producing an optical zoom, for measuring spectral properties, the measuring color, for measuring polarization, for measuring wave fronts for measuring material properties and/or for aberration correction. Other components of the image conversion module are at least one image sensor, an optical interface which can be optically coupled to a lens of the microscope, a data interface for transmitting the data provided by the image sensor, and a mechanical interface for mechanically placing the image conversion module on the microscope. The invention also relates to a microscope comprising said type of image conversion module.
