DESCRIPTION:
 
The Model 758.1 is an eyesafe laser rangefinder receiver optimized for ultra high sensitivity and narrow pulses. 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. TTL/CMOS compatible output is provided for a range counter. The Model 758.1 is designed to meet the demanding requirements of military applications and offers among the highest sensitivities 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. An  evaluation PCB is available.
