Thermoelectrically cooled NIR (near infrared) detector with low noise and high-speed response

InGaAs PIN photodiodes have small terminal capacitance for high-speed response and also feature high shunt resistance and very low noise. The G8605 series of InGaAs PIN photodiodes are thermoelectrically cooled types that decrease the dark current to achieve high D . One-stage (-10 °C) and two-stage (-20 °C) thermoelectrically cooled types are provided.
