Varifocal lenses offer maximum flexibility in camera installations requiring
a wide range of focal lengths. Focal length adjustments can be made with a turn
of the dial, virtually eliminating the cost and inventory problems associated
with improper monofocal lens selection. All lenses are CS-Mount, comprised of
all glass optics, come with locking set screws and a durable metal barrel and
mount, and are covered by a three-year warranty.
Varifocal Lenses are available in a variety of focal lengths.
To determine the right lens for your application, select iris types from the
Varifocal Lens Chart below.
Infrared Lenses (-IR series
below) are designed for use with Day/Night cameras. They eliminate focus shift
in night mode, especially in the presence of IR lighting.
Manual Iris Lenses are used primarily for indoor use with stable
or moderately variable lighting conditions.
DC & Video Auto Iris Lenses are used for indoor or outdoor applications where
large variation in lighting occurs.
