SZ 182



The Questar SZ 182 Multi Focal Length Optical System is a fully motorized, parfocusing; microprocessor controlled Maksutov Cassegrain Catadioptric Optical system with a clear aperture of 178 mm and a base focal length of 2400 mm at F/13.5. It is the most rugged and sophisticated long range surveillance lens available in the medium aperture market today. It is able to read license plates at 2.5 km and identify ships at 20 km. It is vailable in both a permanent site fully integrated system or a rapid deployment stand-alone configuration for mounting on customer supplied equipment. Its optional accessories give it versatility and usefulness that can be customized to meet any individual requirement. It will have state of the art electronics based on the Pentium processor and will be modular
designed for easy upgrades. Each unit will come with hardware that will allow it to be controlled locally from a lap top computer's Com port or modem for longer distances Tele-communication. The software will be a Windows 95/98 and Visual Basic based platform. The keyboard and mouse will be used to access the command menus..

The SZ 182 system comes equipped to connect to any standard video camera with C mount lens thread and will support most CCD formats. Camera is purchased separately. The system is equipped with five selectable focal lengths and filters. The internal optical components and baffling system have been designed to maximize light transmission and minimize all optical aberrations to increase overall system performance to unprecedented 1/6 wave PV minimum. The internal mechanics allow this unit to tolerate high G loads while maintaining boresight accuracy at each focal length. The enhanced mechanics provide for a rapid focal length and focus transition when in the Par focal mode, generally not to exceed 1 second. The system software will have the ability to control or monitor
features such as Time/Date, Temperature, Enclosure Pressure, Multi camera switcher, Automatic light control (ALC), Wide field target acquisition finder camera, automatic sun sensor, heat/ cooling control, lens cap, Pan/Tilt, communication, and video camera control functions. Some cameras will require special or adapted software and hardware.
