A Linnebach lantern or Linnebach projector is a lensless projection system used in theatrical productions. It was developed by (and named after) Adolf Linnebach in the early 20th century. Since the middle of the 20th century, it has largely been replaced by other projection technologies.
The lantern consists of a long case that is painted black on the inside. The case contains a high-powered lamp. One side of the case is a transparent slide with the image that is to be projected. Projection is often done from behind onto a translucent material. A system of lenses can optionally be used to prevent distortion of the projected image.
Famous quotes containing the word lantern:
““... It may be Prester John’s balloon
Or an old battered lantern hung aloft
To light poor travellers to their distress.”
She then: “How you digress!””
—T.S. (Thomas Stearns)
