u Varifocal lenses with 960H optical resolution
u High-quality optics
u 1/3-inch formats
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 wideangle 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

u DC-iris models
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 fourpin 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

moving the camera set-up. If the field-of-view 
requirements change after installation, modification is 
simple by just altering the lens’ focal length settings.
IR corrected
All lenses in this range are IR corrected to match the 
wide range of light conditions covered by our cameras. 
Infrared corrected lenses provide fully adjusted and 
sharp focused images in daylight and at night when 
used in conjunction with IR illuminators. This makes IR 
lenses the best choice for high performance day/night 
cameras.
Robust
The mechanical construction is designed to withstand 
both frequent iris control operations and the 
environmental stress of security installations. For 
flexible, high-quality, reliable lenses that match a 960H 
camera’s performance, this family is the ideal solution.
