Vari-focal lenses are the most versatile
and practical lenses to use when the
job calls for optimization of angular
field on site. Surveillance effects are
maximized since any desired angle of
field can be obtained. There is no
need to carry several different focal
length lenses for an installation job.
Installation can be more efficient
because the installer can find the
desired angles of field without moving
the camera set-up. Once installed,
even if the field of view requirements
change, the system can still be used
simply by altering the focal length
setting of the lens.
This lens series are compact, rugged,
1/3-inch and 1/2-inch image format
manual and DC iris varifocal lenses.
Their high sensitivity and reliability
provide optimal performance in all
environments.
These lenses are provided with a
standard CS mount for use with a
wide variety of cameras. The
connection for the DC iris control are
is a 4-pin standard plug that fits
directly into the cameras iris output.
Impressive optical quality is a result of
combined high standards for
resolution, contrast reproduction and
lens coating.
The mechanical construction has been
designed to withstand the frequent
control operations of the iris, zoom,
and focus operations.
For a cost effective lens that provides
the high quality and reliability needed
to enhance camera images, these
lenses are the ideal solution.
