Description
With the introduction of true day/night cameras, CCTV cameras have become more
versatile - and now lenses must match the wide range of light conditions covered
by those cameras. (Infrared) corrected lenses provide fully adjusted and sharp
focused images in daylight and at nigh when used in conjunction with IR
illuminators. This makes IR lenses the best choice for high performance true
day/night cameras.
The IR range includes 1/3-inch and 1/2-inch format lenses. The 1/3-inch lenses
are used exclusively for 1/3-inch type cameras. The high design standards of the
1/2-inch lenses make them a perfect match for both 1/3-inch and 1/2-inch type
cameras. When used with 1/3-inch type cameras, the 1/2-inch lenses provide a
more "telephoto" effect.
For auto iris control, all lenses use the standard four pin EIAJ connector,
which fits directly into the camera's iris output. Varifocal lenses are DC iris
direct drives, while zoom lenses have Video-iris drives.
For zoom focus and pre-position control, the lenses are fitted with an 8-pin DIN
connector. The 18x zoom lens also features manual iris override. Impressive
optical quality is a result of ED glass elements, aspherical lenses, and
multi-layer coatings. These lenses maintain focus to IR wavelengths of 950 nm.
The mechanical construction is robust enough to withstand frequent control
operations of the iris, zoom, and focus functions.
