  • F-Mount Periscope
Apr 2010
Resolve Optics Ltd.Request Info
CHESHAM, England, April 27, 2010 — A ruggedized F-mount periscope has been supplied from Resolve Optics Ltd. to Specialised Imaging Ltd. to provide real-time focusing of any prime lens on the latter company’s SIR3 high-speed ballistic range camera.

The rugged, lockable F-mount focusing system for the SIR3 incorporates a manual iris adjustment to enable the use of any prime lens, including the DSLR lenses that have no manual iris control.

A micro switch, activated by the mirror slide, was incorporated into the design to ensure that the camera cannot be used while the mirror is in the focusing position.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
An optical instrument designed to displace the line of sight in a vertical direction. For submarines and other military uses the periscope is a long tube containing prisms at both ends and intervening imaging and relaying lenses. Several anatomical inspection devices such as cystoscopes, laryngoscopes and otoscopes use similar optical systems, though on a minuscule scale.
