The AP300-1-T2 is an amplified InGaAs sensor with a 2-stage thermo-electric cooler (TEC). A low noise amplifier provides detector-noise limited performance in a compact package. The 2-stage TEC ensures low noise operation up to 2.6um and a large 1mm2 active area provides generous light collection. All that is needed is a DC power supply. OEM custom configurations welcome. Please contact us to discuss your requirements.
