Abstract
An optical system for a display device for head mounting is described. In particular a Maxwellian display device, with an enlarged eye-box is described. The optical system includes a beam forming element configured to converge multiple sets of light beams into at least two points of convergence (e.g., on an exit pupil of the optical system or of the display device using the optical system), and at least one optical arrangement comprising an input for input light beams, at least one beam splitter and at least three reflectors. The at least one beam splitter and at least three reflectors are positioned to form the multiple sets of the light beams from the input light beams such that the multiple sets of the light beams have equally long beam paths from the input to the beam forming element. Each point of convergence is a convergent viewing point for a user, thus enlarging the eye-box.
