Varifocal 960H Lenses
www.boschsecurity.com
This family of 960H lenses comprises varifocal lenses
with DC-iris control. They are compact, rugged lenses
in 1/3‑inch image formats. The lenses range from wide-
angle to telephoto to cover virtually all applications in
CCTV observation systems.
The lenses deliver impressive optical quality due to
their 960H resolution, contrast reproduction, and
coating.
System overview
Higher resolution sensors, with even smaller pixel
sizes, require higher resolution lenses to deliver their
full potential. The lenses in this family are specifically
designed for the Bosch range of 960H DINION
cameras. To get the maximum resolution from a 960H
camera, you need to select a lens which can match
sensor resolution not only at the center, but also at
the edges and at different iris openings.
The Modulation Transfer Function (MTF) specification
is an indication of the resolution, contrast, and
sharpness performance of a lens. Lens resolution is
normally measured in line pairs per millimeter (lp/
mm). The MTF of each lens gives the maximum
resolution in terms of lp/mm for a given scene.
Both the LVF-4000C and LVF-5000C range have
excellent daytime resolution. The LVF-5000C range is
best suited to wide dynamic range (WDR) cameras and

cameras that are used to capture more details at
night. The LTC 3664/31 lens offers excellent
performance in low-light scenes with an aperture of
F1.0.
The measured MTF specifications are only one aspect
of a lens's quality. Special anti-reflective coatings to
reduce flare, better aberration performance and lower
distortion also contribute to their suitability for
different cameras.
Functions
DC iris control
For auto iris control, all lenses use the standard four-
pin EIAJ connector, which fits directly into the
camera's iris output.
Wide range
The extent of the range means that an installer is
always able to select the most appropriate lens for
both camera and application.
For optimizing angular fields right on site, varifocal
lenses are the most versatile and practical solution
available. These lenses allow for setting virtually any
angle of field, which maximizes surveillance effects.
Installers do not need to carry several different focal
length lenses – and installation is more efficient
because they can find the right angles of field without
