For optimizing angular fields right on site, varifocal lenses
are the most versatile and practical solution available.
These lenses allow for setting virtually any angle of field,
which maximizes surveillance effects. Installers do not need
to carry several different focal length lenses – and
installation is more efficient because they can find the right
angles of field without moving the camera set-up. If the
field-of-view requirements change after installation,
modification is simple by just altering the lens’ focal length
settings.
Functions
This series includes both manual and DC-iris varifocal
lenses. They are compact, rugged, and available in 1/3-inch
and 1/2- inch image formats. The series is organized by
sensitivity, optical resolution, and range to match the wide
range of Dinion camera applications.
These varifocal lenses come with a standard C or CS mount
for use with a variety of cameras. The DC-iris control
connection is a four-pin standard plug that fits directly into
the camera’s iris output. And the lenses deliver impressive
optical quality due to their high standards for resolution,
contrast reproduction, and coating.
The mechanical construction is designed to withstand both
frequent DC-iris control operations and the environmental
stress of security installations. For flexible, high-quality,
reliable lenses that match a camera’s performance, this
varifocal series is the ideal solution.
