G8605_11 Datasheet, PDF (1/5 Pages) Hamamatsu Corporation – Thermoelectrically cooled NIR (near infrared) detector with low noise and high-speed response

InGaAs PIN photodiodes
G8605 series
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 cur-
rent to achieve high D . One-stage (-10 °C) and two-stage (-20 °C) thermoelectrically cooled types are provided.
