Abstract
The present invention relates to an optical ocular system having imaging optics that map an image generated in an object plane such that a user can perceive the same in an image plane, wherein the imaging optics comprise a first lens having negative refractive power, and a deflection element having positive refractive power, which is connected downstream of the first lens, effecting a folding of the optical path by means of a single reflection, wherein the first lens and the object plane form a first optical group, and a displacement unit is provided, which can change the distance between the first optical group and the displacement element for the correction of spherical ametropia of the user.
Claims18
An optical ocular system having imaging optics, which image an image generated in an object plane so that a user can perceive it in an image plane, the imaging optics comprising:
- a first lens having negative refractive power and a deflection element, which is downstream from the first lens, having positive refractive power, which causes folding of the beam path using a single reflection,
- wherein the first lens and the object plane form a first optic group and further comprising a displacement unit, which changes the spacing between the first optic group and the deflection element to correct spherical defective vision of the user.
