DESCRIPTION:
 
The Model 758A.1 is a new generation of eyesafe laser rangefinder receivers optimized for ultra high sensitivity, excellent overload performance and exceptional ability to discriminate between two close targets.  Pulsewidths from
1 to 40ns are processed over seven orders of magnitude dynamic range, and operation is possible from 1.0 to
1.6mm. The detector and critical pre-amplifier components are thermoelectrically-cooled to minimize noise using a built-in temperature sensor and controller. A choice of different sizes of InGaAs APD detectors is available to achieve optimum performance in different rangefinders.  Time-programmed gain is triggered at TO to eliminate false echoes
at short ranges.  Linear outputs are available for custom applications. Low-impedance output is provided for a range counter.  The Model 758A.1 is designed to meet the demanding requirements of military applications and offers the highest sensitivity of our family of rangefinder receivers. The small size and PCB mounting make it ideal for compact
systems  requiring  high  target  fidelity  and  maximum  performance.  The  Model  758A.1  is  used  in  AMI’s  high
performance range counter module. See Model 7558 Laser Rangefinder Receiver-Range Processer Module.
