Abstract
1,060,932. Optical projection apparatus. E.J. ANTON. April 13, 1965, No.15782/65. Heading G2J. The magnification of the image projected on a screen 33 is increased by the use of a negative plano-concave element 35 adjustably mounted beyond the focal point 31 of a Petzval-type objective lens system. The cine projection system shown has a condenser 7, shutter 9, film gate 17 and lens aperture 19. Slide projection is also possible.
