CVO lenses for use with megapixel CCTV
A
Stemmer Imaging product story
Edited by the Engineeringtalk editorial team
Mar 10, 2009
Stemmer Imaging has introduced the CVO (Common Vision Optics) range of megapixel CCTV lenses, including two day/night variants.
These high quality lenses produce high resolution and high contrast across the entire field of view.
This makes them perfect for use with megapixel cameras and lets them take advantage of the enhanced resolution and reduce the number of cameras required to cover a particular field of view.
The day/night lenses feature a version with DC iris and a focal length of 3-8mm and a varifocal version with a manual iris and focal length of 4.5-13mm.
The varifocal capability is a benefit if there is little flexibility in the mounting position for the camera, since the focal length can be adjusted to suit the application.
Day/night lenses are ideal for security surveillance applications, as they can focus visible and infrared light, thus preventing blurring by compensating for the differences in wavelengths from daylight, moonlight, halogen car-headlights and sodium street-lighting.
The CVO megapixel lens range is completed by a 1/2in (12.7mm) focal-length version with manual iris.
This lens offers a 185-degree (fish-eye) field of view to eliminate dead angles and provide effective wide-area surveillance.
