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.
