Varifocal lenses
offer the maximum flexibility for the CCTV installer as
they can be adjusted to match the exact scene required
by the end user. Once obtained, the view can be fixed by
means of the lens locking screws. Computar offer one of
the largest ranges of varifocal lenses from a 1.8mm
(almost fish eye) to 50mm for close up views. Whatever
the application Computar has a varifocal to match your
needs.
IR Corrected Varifocal
Commonly known
as Day/Night lenses. All of the features of a
traditional varifocal lens are available but with the
added benefits of IR correction. These lenses are
manufactured with a special E.D. glass and lens coating.
This combination allows the lens to deliver perfect
focus under normal lighting and also under IR
illumination.
In general, Computar's range of
varifocal lenses either in standard or IR versions
offers the installer an extremely wide choice of lenses
to match the ever changing installation applications.

Including
Manual and Motorised Zoom Lenses

Zoom lenses differ
from varifocals since once they have been set up by the
CCTV installer, they will always stay in focus no matter
how often the zoom ratio is changed. Zoom lenses give
you the ability to view and get close ups of objects to
highlight details or identification even when the object
is some distance away. These are ideal for covert
applications where your camera cannot be installed close
to your target.
Manual Zoom lenses
Computar's
manual zoom lenses allow the CCTV installer to manually
adjust the focal length, iris and focus. Ideal to view
areas where you require high quality images with the
flexibility of local adjustment. Applications include
inspection, machine vision and covert.
Motorised
Zoom Lenses
Computar's Zoom lenses are predominantly
used in conjunction with pan & tilt units (movable
cameras) when the system is controlled remotely by an
operator who can automatically adjust the picture to the
desired view. These lenses are ideal when covering large
areas, but still require the ability to alter the view
for identification of images like city centres,
Industrial sites, Car Parks and areas of low light.

The Megapixel lenses
(high definition) are designed to capture the full
resolution of megapixel cameras, providing a high
contrast and a sharp picture.
The Wide-aperture
(F1.4) design of the Megapixel lenses help to achieve
clear images under low light levels. These lenses also
provide good image recognition accuracy that is achieved
by the reduction of distortion and improvement of
illumination uniformity over the CCD sensor. Another
important feature is the robust enclosure that is
resistant to vibrations and shocks making it ideal for
use in Video imaging equipment and machine vision
applications.

Telecentric
& Macro Lenses
|
|
Pinhole lenses for
security and industrial
applications. The lenses are
designed for
the highest quality images where the
viewing area is no more than a pinhole.
The lenses
can be used on both colour and monochrome cameras

| Fixed focal length
lenses offer the CCTV installer fixed images of a scene.
These lenses are an ideal solution when the views are
known such as a Fire Exit door or an entrance foyer. All
Computar fixed focal lenses have a manual adjustment of
the focus for crisp clear images and locking screws to
hold position. Computar offer an extremely wide range of
fixed focal lenses for all types of applications and
installations.
