1. 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,
an input device for inputting the first refractive index to a controller, and
the 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.
