OZ Optics DD series of compact PC board mountable motor driven variable attenuators with low backreflection offers excellent speed, repeatability, and accuracy. Single mode and polarization maintaining (PM) attenuators utilize a novel blocking style attenuation technique, while multimode attenuators use a variable neutral density filter to minimize mode dependent losses. Both types feature a homing sensor to calibrate the attenuator, removing the need to use external taps, and a jam-proof tuning mechanism.The PC version uses a reliable stepper motor that can be controlled by an external driver. The basic model allows direct access to the stepper motor, as well as a logic level output for HOME position information. The -DR option adds a high-speed driver circuit that accepts four logic level inputs to control the stepper motor. Finally, the -MC option features an embedded microcontroller with a programmed calibration curve. The units are addressable and support RS232, SPI, or I²C communication protocols.AMS Technologies and OZ Optics can also customize the design to fit your needs. There are smaller and faster versions if lower resolution is acceptable. Contact AMS Technologies for detailed specifications.
