Laser Rangefinder Receivers With Range Processors

The 7558 and 7555 Series Rangefinder/Processor assemblies comprise a high performance Model 758A or 755A receiver with compact support electronics to provide corrected range data to a mother system. The serial range data output is calibrated using AMI’s patented technology to mitigate the effects of range errors from various sources including walk due to return signal amplitude variations. Exceptional sensitivity allows the use of low power lasers, or alternatively, long range operation. The modules provide high voltage bias, time programmed gain with noise tracking threshold, first, last, and strongest pulse selection and range gating. The 7558 series offers a TE cooler controller and heatsink. There also are a number of user controlled options via the serial interface. The compact layout allows positioning at the optics for minimum overall system size.
Custom options and optimization are available.
