HAMAMATSU P4631-01, P4631-04, P4631-03, P4639, P4638 Datasheet

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,

2

MCT, InAs and InSb, which are all combined with a thermoelectric cooler. P4631-10 using an MCT detector is especially suited for CO

laser

detection. We welcome requests for custom devices that suit your application.
