Dual wavelength InGaAs APD receiver supports eye-safe laser range

CMC ELECTRONICS 264-339814 series Dual Wavelength InGaAs Avalanche Photodiode (APD) Preamplifier Module supports accurate and consistent eye-safe laser range finding and LiDAR designs under a variety of moisture and altitude conditions. Device facilitates accurate decision making due to the speed and precision of the information it provides in low signals or high, warm weather or cold and for distances near or far. Receiver combines high-density microcircuit with advanced overload recovery optoelectronics in a compact, ruggedized and hermetic TO-8 package. Device can detect high speed, ultra-low light signals more precisely than any other device of its kind.

This eye-safe device works at both 1064nm and 1570nm and enables longer distance measurements in these two wavebands quickly, accurately and consistently. The built-in thermoelectric cooler (TEC) takes the guesswork of APD temperature compensation out of the equation, facilitating more compact system designs. This also allows the receiver to deliver reliable performance over a wide range of temperatures. Devicew can quickly recover from miliwatts of laser bursts in nanoseconds time without damage and can detect signal power in the low nanowatt range. Device’s compact microcircuit design minimizes parasitic noise, thus giving superior signal-to-noise ratio performance.
