Abstract
An imaging optical system for a display device that can be fitted on the head of a user and generate an image, with an optical element, which includes an entry surface, and a spectacle lens, which includes a coupling-out section. The imaging optical system is configured to guide the generated image fed to the optical element via the entry surface in the optical element, and to couple it from the latter into the spectacle lens, in which it is guided to the coupling-out section and coupled out via the coupling-out section to generate a virtual image. The optical element includes, in addition to the entry surface, at least one reflecting surface, on which the generated image is reflected for guiding in the optical element, and in that the optical element and the spectacle lens are formed together as a one-piece optical part.
