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. 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.

FEATUREs
● High-speed response
● Low noise
● Various active area sizes available from φ1 to φ5 mm

APPLICATIONs
● Optical power meter
● Water content analyzer
