G6122 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – Infrared detector module with preamp

INFRARED DETECTOR
Infrared detector module with preamp
Thermoelectrically cooled type
Easy-to-use detector module with built-in preamp
Infrared detector modules operate just by connecting to a DC power supply. The detector element is selectable from among InGaAs, PbS, PbSe,
MCT, InAs and InSb, which are all combined with a thermoelectric cooler. P4631-10 using an MCT detector is especially suited for CO2 laser
detection. We welcome requests for custom devices that suit your application.
Features
l High S/N
l Compact size
l Easy to use
Operates just by connecting to DC power supply
l Circuit design optimized for detector element characteristics
l Built-in thermoelectric cooling control circuit (fixed control
temperature)
Applications
l Infrared detection
l CO2 laser detection
Accessories (Supplied)
l DC power cable (2 m): A4372-03
When using a power supply other than Hamamatsu C3871-03/
-04 power supplies designed for IR detector modules, use a
mating connector (Hirose Electric RM12BRD-6S).
