Lenses
 Varifocal
lenses offer maximum flexibility in camera installations requiring a
wide range of focal length adjustments. 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
and come with a durable metal barrel and mount.
Two versions are available - Manual or DC
driven Auto-Iris lenses. An Auto-Iris lens automatically detects the
amount of light entering the lens and adjusts accordingly to allow
just the right amount of light to provide you with a clear view.
They are ideal for outdoor applications. If the light is always the
same (such as in most interior applications), a manual or fixed iris
lens is appropriate.
If you don’t see the lens you need, do not
dismay. We can provide you with any CCTV lens for any application.
Simply contact us.
Give us the dimensions of the area you want to view (Height X Width)
and how far away the camera will be from the center of that view.
We’ll tell you what lens you need and provide you with a few
options.

Varifocal Auto-Iris lenses

3.5-8mm Day/Night Auto-Iris Varifocal Lens
The Day/Night Cameras which function as
color cameras in the daytime and high-sensitive monochrome cameras
in the night, now come onstage as the surveillance systems expanded
in their applications from the daytime to the night. However,
ordinary lenses do not reproduce crisp images under IR Illuminations
as sharp as the images under visible lights during daytime. That is
due to chromatic aberration that causes the shift of focusing points
under visible lights and IR Rays. This Day/Night lens is chromatic
aberration corrected extensively in a wide range from visible lights
to near IR Rays and is designed to reduce the focus shift to the
unrecognizable level. It displays outstanding optical quality and
performance in the range from visible lights to near IR Rays.
