Abstract
An HMD device including an image-generating unit for generating a polychromatic image and deflection optics having first and second partial optics. The deflection optics project the image such tat it is perceivable by a user wearing the HMD device. The two partial optics each contain a diffractive optical unit for beam deflection, which are designed such that their dispersion errors compensate each other.
