  • Patent number: 11300782
    Abstract: 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.
