u High Quality Optics

u Reliable, Robust Construction

u 1/3-inch Format with DC-iris Control

These Motorized Zoom Lenses are compact, rugged,
1/3-inch and 1/2-inch image format auto iris lenses.
Their high sensitivity and reliability provide optimal
performance in all environments.
The 1/3-inch DC-iris Series Lenses have been designed
for more economical uses and are provided with a
standard CS mount for use with a wide variety of
cameras.
The 1/2-inch Video-iris Series are high quality lenses,
and are provided with both CS and C mount options.

Functions

For the auto iris control, all lenses use the standard 4­pin EIAJ connector which fits directly into the
camera’s iris output. For zoom, focus, and pre-position
control, the lenses are fitted with an 8-pin DIN
connector.
Impressive optical quality is a result of combined high
standards for resolution, contrast reproduction, and
lens coating. The lenses have been designed to match
with the complete range of Bosch cameras. When used
in combination with the 1/2-inch Series cameras they
provide the necessary large F/stop and high quality
camera optic features.
Lenses in this series include 10x, 15x, and 20x zoom
range models. Some models provide optional pre­position and manual iris override functions.

u 1/2-inch Format with Video-iris Control

u 10x, 15x, and 20x Zoom Ranges

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.
