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.
The LTC 337x Series are compact,
rugged, 1/3-inch image format Manualand DC- iris lenses with a wide
coverage of 5 - 50 mm. Their high
sensitivity and reliability provide
optimal performance in all
environments. A better picture quality
is achieved by using 2 aspherical
lenses.
These lenses are provided with a
standard CS-mount for use with a
wide variety of cameras. The
connections for the DC-iris control
are available as either 4-pin standard
or 6-pin plugs. They fit directly into the
cameras iris output.
Impressive optical quality is a result of
combined high standards for
resolution, contrast reproduction and
lens coating. An f/stop of F/1.4 gives a
brighter contrast range.
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.
