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 multi­layer 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.
