Abstract
Optical lens system of wide angle for the projection of slides, which is essentially characterized by the fact of behaving a set of flat convex glasses of aplanatic type, conjugated properly with the projector to be able to come to stand in front of the slide, placed before the appropriate capacitor, with respect to which the aforementioned objective of greater dimensions is, arranging the machine's own and current objective so that it can also be aligned with respect to the emitting source and be separated from the rays coming from it, so that the projection of the image on a small screen can be carried out with the usual elements, while using panoramic or super-panoramic screens, to cover the entire field of the same, the additional objective is inserted into the light beam, which, due to its wide-angle, allows the image to cover the entire field of such screens, starting from slides of appropriate dimensions, preferably 31x74 mm, the mechanical part of said optical system being formed by two arms of which one is a carrier of the aplastic lens and is articulated to the apparatus, while the rest is integral with the usual objective and is applied to a fixed point, either from the same projecting machine or from the corresponding cabin wall.
