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 ˚C)
and two-stage (-20 ˚C) thermoelectrically cooled types are provided.
Features
l High-speed response
l Low noise
l Various active area sizes available from φ1 to φ5 mm
Applications
l Optical power meter
l Water content analyzer
