Patent ID: 8066374

Claim:
An optical system for reflection-free ophthalmoscopy having a beam path with reflective, or refractive and reflective, optical elements which are used substantially in common for illumination, observation, and/or recording, the optical system comprising: a plurality of reflecting optical elements, or a plurality of reflecting and refracting optical elements, for illuminating and imaging the fundus; wherein the plurality of reflecting, or reflecting and refracting, optical elements comprises a mirror system including at least two freeform mirror optical elements which are formed as freeform mirrors, each with an imaging, reflecting freeform surface; wherein the optical elements are arranged in a housing in a precisely defined position and attitude relative to one another in such a way that an imaging of reflecting surfaces of the optical elements on the image of the retina is prevented within a diopter range of the patient's eye to be examined; and wherein the freeform mirrors are formed as symmetry-free freeform mirrors between which an intermediate image plane is located.
