Diapol 9839 Automat automatic slides projector

A slide projector is an optical device for displaying enlarged images on a screen. The design of projectors in the Diapol series was the joint work of Witold Woźniakowski, Jan Figlewicz and Zbyszek Kramarz. The external design of the projector was prepared by Jan Krzysztof Meisner. The Diapol 9839 Automat projector is designed for projecting black-and-white or colour positive slides in the 24x38 mm format, framed in 5x5 cm frames. The projector's optical arrangement uses the Krytar 2.8 lens with a focal point of 85 mm from 0.5 to 10 m. The device is equipped with a frame for the automatic feeding of slides. Thanks to the use of a strong halogen lamp, the projector can be used in home conditions, as well as in educational facilities. Manufacturer: Polskie Zakłady Optyczne, Warsaw, 1981 Inv.
