PHOTODIODE
InGaAs PIN photodiode
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.
G8605 series of InGaAs PIN photodiodes are thermoelectrically cooled types that decrease the dark current to achieve high D
*
. One-stage (-10 藲C)
and two-stage (-20 藲C) thermoelectrically cooled types are provided.
