Abstract
A stereo-projection device comprises at least one light source, at least one collimator for converting visible light generated by the light source into light with a substantially parallel beam path, and at least one interference filter which is transparent at a given angle of incidence for at least one wavelength interval having an interval width of at most 50 nm and which is designed to cross the light with the substantially parallel beam path.
