InGaAs Infrared Sensors Target Hunting, Long-Range Shooting Apps
Used in demanding defense, telecom, and industrial applications, Phlux Technology's Noiseless InGaAs infrared sensors can also supplement advanced hunting and professional shooting optics. Able to detect faint infrared signals in the 1550-nm range, indium-gallium-arsenide (InGaAs) avalanche photodiode (APD) technology delivers an order of magnitude higher sensitivity than legacy near‑infrared detectors.
First adopted in laser range finders in the defense industry and optical test equipment for fiber‑network monitoring, the sensors will operate in laser rangefinders, integrated ballistic scopes, and specialist low‑light targeting systems, too. Specialty versions have been developed to address these applications, as hunting and shooting optics have come to rely on laser range finding and digital fire‑control.
By operating at around 1550 nm, an eye‑safe infrared wavelength, system designers can legally and safely use higher laser powers than when using traditional 905-nm solutions. The combination of ultra‑low noise and high internal gain enables the detection of weaker return pulses, for an extended effective ranging distance, smaller-sized optics, and reduced power consumption.
