Abstract
Abstract An improved adapter is provided for joining an optical scope, such as a borescope, endoscope or the like, to a film or video camera. The adapter includes a multi-element relay lens assembly which directs real images viewed by the attached optical scope to the camera for filming. The multi-element relay lens assembly is longitudinally positionable within the adapter to provide a focusing control. A filter slot is further included within the adapter to allow for the insertion of an optical filter between the borescope and the camera without uncoupling either attachment from the adapter. In order to achieve improved image resolution at the camera aperture of images detected by the borescope, a scope's eyepiece optics and the camera lens are removed prior to coupling the borescope and the camera to the adapter. The adapter is capable of use with virtually all sizes and types of cameras and optical scopes, and attachment of the adapter to the camera and the borescope is effected in a manner allowing for selective rotational orientation of each element with respect to the other.
