Optical group for projection apparatus, characterized essentially by being constituted by one or more converging lenses, foreseen dimensions and focal distances, whose lens or lens system is interposed between the objective and the image to be projected, which can be fixed or mobile, the intercalation giving rise to the reduction of the focal distance of said objective and, therefore, to the proportional increase of projection angle and of the projected image on the corresponding screen.
