Light Projection Through Telescopic Lens, 1685

Light Projection Through Telescopic Lens, 1685

Projection of light through a telescopic lens. Interior of a room with telescoping lens mounted on a wall; light passes through the lens onto an apparatus against the opposite wall; other telescopic equipment is on the floor. Johann Zahn (1641-1707) was a German monk and author of Oculus Artificialis Teledioptricus Sive Telescopium (1685) which contains descriptions, diagrams, illustrations and sketches of both the camera obscura and magic lantern, along with various other lanterns, slides, projection types, peepshow boxes, microscopes, telescopes, reflectors, and lenses. The first camera that was small and portable enough to be practical for photography was envisioned by Zahn in 1685, but it would be almost 150 years before technology caught up to where this was possible to build.
