B-2 Bajka picture projector

A projector is an optical device for projecting enlarged images on a screen. Invention of this device is ascribed to either Athansius Kircher, who described and illustrated a device reflecting sunlight in a mirror through lenses onto a screen, or to Christiaan Huygens, who presented the first working "magical lantern" in 1659. A prototype of the Bajka picture projector presented here was built in 1953. Its design was developed by Wiktor Bielecki and Tadeusz Zaborowski. Displaying images is possible thanks to a purpose-built optical projection arrangement comprising a concave mirror and a lightbulb placed parallel to the condenser (an optical element for homogeneous lighting of the film). The focus of the projected image is manually adjusted using a rotary, screw-in lens. Manufacturer: Łódzkie Zakłady Kinotechniczne, Łódź, 1963 Inv.
