A microscope and a microscopy method for imaging an object, wherein use is made of a microscope comprising an objective which defines an optical axis and a focal plane perpendicular thereto, and an adjustable correction optical unit which, at the objective, corrects a spherical aberration occurring when imaging the object with a certain depth position of the focal plane. The method comprises the following steps: determining an actual type of object; reading a database in which refractive indices of different types of objects are stored in order to determine the refractive index of the object; using a relationship between the refractive index and the spherical aberration caused by the object in order to ascertain an adjustment value of the correction optical unit such that there is a reduction in the spherical aberration in the focal plane; adjusting the correction optical unit to the adjustment value; and imaging the object.

Microscopy method and microscope for imaging an object

An apparatus for transmitted light illumination for light microscopes A diaphragm edge may be variably positioned in the direction of the optical axis, wherein a position of the diaphragm edge in the direction of the optical axis can be varied irrespectively of a position of the diaphragm edge transversely to the optical axis. A separate sample support table may be mounted on a housing. The housing has a passage opening, through which the diaphragm edge can be moved in the direction of the optical axis. A holding device is formed in the region of the passage opening of the housing or on a separate sample support table and a control device is present which is adapted to position the diaphragm edge in dependence at least upon a determined presence of a sample support table.
