was an early motion picture
system created by Woodville Latham
and his two sons through their business, the Lambda Company, in New York City
in 1894 and 1895.
Originally called the Panoptikon, it is perhaps the first widescreen
film format, with an aspect ratio
of 1.85. It had a film gauge of 51 mm and an aperture of 37 mm by 20 mm. It was instrumental in the history of film in that it created what became known as the "Latham loop
", which are two loops of film, one on each side of the intermittent movement
, which act as a buffer between continuously moving sprockets
and the jerky motion of the intermittent movement.
