u High-quality optics
u 1/3-inch and 1/2-inch formats
u Reliable, robust construction
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 several 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.
u Focal length options
u Compact design
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.
