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.
