Periscope Delivery

Photonics Spectra
Mar 2011
Carl Zeiss Optronics GmbH of Oberkochen, Germany, an optical and optoelectronics product supplier, will deliver stabilized panorama periscopes to the Canadian armed forces. The Peri R17 A2 periscope is equipped with an Attica, a third-generation thermal imager that provides the commander of a Leopard 2 battle tank with night-vision capability for long ranges. The periscope is currently undergoing trials in other user states.


GLOSSARY
optical
Pertaining to optics and the phenomena of light.
optoelectronics
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
periscope
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.
