ANAMORPHIC LENS HAVING A 3D ADAPTER FOR 35MM AND BEING INTENDED FOR A MOVIE PROJECTOR AND VIDEO PROJECTOR

摘要

The invention relates to a three-dimensional lens for a standard 35mm projector as well as for a video projector, for exclusively transferring high-quality left and right 35mm images, which were precompressed and transferred onto a single frame of 35-mm film, onto the screen. A single standard anamorphic lens is combined with an adapter housing positioned immediately in front of the lens. When the two compressed right and left 35mm images from the light source reach the optical system, said images are first decompressed by the anamorphic lens. Both the right and left 35mm images are precompressed by a specific printing system, which compresses two right and left 35mm images instead of reducing the images in order store the latter in a single frame of 35mm film. The decompressed images then pass through the adapter housing. The latter consists of a trapezoidal metal frame, in the middle of which two primary mirrors are joined at a 90º angle. The inclinations of the two secondary mirrors, which are parallel to the two equal sides of the trapezoidal frame and opposite the primary mirrors, are adjustable. Two polarizing filters are mounted at the location at which the optical axis exits the housing. The right and left images are directed towards the screen by means of the set of mirrors and the polarizing filters of the adapter housing, the ray-reflecting interplay of which first divides the two images, and then stacks the images such that the latter may be viewed with very high quality due to the three-dimensional filtering lenses.
