Abstract
The invention relates to an optical system (7) having an optical axis (OA), having a display unit (5) for displaying an image, having an eyepiece (6) for viewing the image, the eyepiece (6) comprising a lens unit (L1). The display unit (5) is designed in such away that a marginal ray light beam (9) emanates from an edge (8) of the display unit (5) and propagates to the lens unit (L1) in a light incidence direction (L). The display unit (5) is arranged first along the optical axis (OA) in the light incidence direction (L), followed by the lens unit (L1) arranged on the optical axis (OA). No further optical unit of the optical system (7) is arranged between the lens unit (L1) and a pupil of the eye (2). The marginal ray light beam (9) has a chief ray (HS). The chief ray (HS) propagates at a first chief ray height (H1) at the lens unit (L1) and at a second chief ray height (H2) at the display unit (5). The first chief ray height (H1) is at least level with the second chief ray height (H2).
