Abstract
An optical system for a microscope for imaging an object includes: a telescope system having an optical correction unit, which is adjustable in order to correct a spherical imaging aberration, and having a zoom optical unit, which is adjustable in order to adapt a magnification of the telescope system to a ratio of two refractive indices, one of which is assigned to an object side and an other of which is assigned to an image side, within a predetermined magnification range. The telescope system is telecentric over an entire magnification range both with respect to the object side and with respect to the image side by the zoom optical unit contained in the telescope system.

An optical system for a microscope for imaging an object, the optical system comprising:
- a telescope system comprising:
- an optical correction unit, the optical correction unit being adjustable in order to correct a spherical imaging aberration, and
- a zoom optical unit, the zoom optical unit being adjustable in order to adapt a magnification of the telescope system to a ratio of a first refractive index and a second refractive index, the first refractive index being assigned to an object side of the telescope system, and the second refractive index being assigned to an image side of the telescope system, wherein the magnification of the telescope system is within a predetermined magnification range, and
- a controller configured to adjust the optical correction unit and the zoom optical unit based on the first refractive index,
- wherein the telescope system is telecentric over the predetermined magnification range, both with respect to the object side of the telescope system and with respect to the image side of the telescope system, by the zoom optical unit contained in the telescope system.
A method for imaging an object using a microscope having a telescope system with an optical correction unit and a zoom optical unit, the method comprising:
- adjusting the zoom optical unit to adapt a magnification of the telescope system within a predetermined magnification range to a ratio of a first refractive index and a second refractive index, the first refractive index being assigned to an object side of the telescope system, and the second refractive index being assigned to an image side of the telescope system;
- and
- adjusting the optical correction unit based on the first refractive index to correct a spherical imaging aberration.
