Manual ZoomZoom lenses offer the possibility to adjust the focal length and so also the angle of view over a wider range. Due to this fact these lenses are suitable for applications in which the object distance can change. Please note the rather large minimal object distance in contrast to the other so far described lenses. If the object distance is below this minimal distance, the taken picture will no longer be sharp. |

Fixed Focal Length with Automatic IrisThe lenses of this group provide an automatic iris, which can be controlled externally. With this feature the brightness of the recorded picture can be adjusted according to the respective surrounding conditions. There are used two different modes to control the iris. Lenses with the so called DC Drive (Direct Drive) need an analogue control voltage. Lenses with Video Drive provide an internal electronic, which converts an external video signal to the respective control voltage. Further informations in our overview |

Variable Focus with Automatic IrisLenses with variable focus allow the focal length to be adjusted within a certain range. A change of the focal length changes also the angle of view. A shorter focal length leads to a wider angle of view, whereas lenses with a long focal length cover only a limited angle of view. The Angle of view of the human eye is approx. 33.4 degree, which corresponds to a focal length of 8mm. Larger Angle of views are often designated as “wide angle”. Lenses with smaller angles of views are sometimes called “Tele”. Further informations in our overview |

Aspherical Lenses with High Speed IrisThese lenses provide a very fast iris. Herewith also fast changes in the amount of incoming light can be compensated by a respective aperture. As with many of the so far introduced lenses also here types with DC and Video drive are available. Further informations in our overview |

Manual Zoom with Automatic IrisThe following lenses are again available as DC drive version as well as Video drive. The optical specifications of both types are the same. Please note also here the rather large minimum object distance. The lenses with C mount can be used with CS mount cameras with a 5mm adapter ring (please refer to the chapter about accessories below) Further informations in our overview |

Motorized ZoomThe lenses out of this group are suitable for surveillance applications. They are e.g. used for observing streets, ports, air fields and borderlines. The following lenses with motorized zoom are available in several different versions, which provide different features. Beside some slightly different values for the iris the optical specifications are however the same. Further informations in our overview |

Pinhole LensesThese lenses provide a small front aperture. With this they can be used to take pictures also through small holes. This can be of great advantage in surveillance applications, as well as for inspecting goods. The small aperture results also in a larger focal depth, which means that pictures can be taken sharp over a quite wide range of distance. A disadvantage is however the low amount of light, which can be collected by the lens. This can yield to long integration times or the necessity to use an external lighting.

Macro LensesMacro lenses provide a low minimum object distance. Because of this they are very suitable for taking pictures of objects from a short distance. The lenses show a quite large front aperture, which means that the front lens has a larger diameter. Further informations in our overview |

AccessoriesFor the lenses described in this overview CBC provides also a series of useful accessories. By using extenders the focal length of a lens can be enlarged. These extenders are mounted between lens and camera. With adapter rings the distance between lens and camera can be enlarged; a special 5mm adapter allows C mount lenses to be used with CS mount cameras. Finally a view finder is available, which can be used to find a suitable lens for a new application. Further informations in our overview |

CCTV for Factory Automation with AccessoriesEspecially for measurement applications in the industrial area CBC provides a series of lenses with a minimal distortion. In addition the modulation transfer, a value to characterize the quality of a lens, are much better that with ordinary CCTV lenses, which are mainly used for surveillance applications. Most of the lenses of this group are designed to be used with the modern high resolution mega pixel cameras. Further informations in our overview |

CBC provides more products for factory automation and surveillance. Please contact us, if you have interest in these products. We will then send you closer information.
Cameras
CBC offers a wide range of cameras produced by GANZ, which are optimized for applications in surveillance. These cameras can however also be used in the industrial area. For surveillance applications small cameras in dome housing are available. Cameras in ordinary housings are suitable to be used e.g. in the industrial quality control. For a direct connection to the internet or other networks special IP cameras can be supplied, which deliver the pictures directly in the compressed MPEG or M-JPEG format.
Infrared lightings
For illuminating scenes with invisible infrared light CBC provides compact and powerful infrared lamps, which are suitable for a non stop operation in the outside.
Monitors
CBC can deliver the classical tube monitors as well as modern LCD displays. All models are made for non stop use even under worse conditions. For mobile use light and compact service monitors are available.
Recording devices and further accessories
For recording video signals CBC supplies analogue as well as digital recorders with a recording time of up to 480 hours. Telemetric systems allow a wireless transmission of video signal over up to 1000m distance. Video splitters for displaying several video pictures on one monitor and multiplexer to switch between different video sources complete the range of supply.
