Abstract
The design of an optical probe/camera objective having good image quality over an extended focusing range is described. Bearing some resemblance to a periscope, it simultaneously provides an image to both vidicon tube and photographic film. The entire system is used in the production of television commercials where a certain type of special effects may be required.
