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

Features
Applications
High S/N
Infrared detection
Compact size
CO2 laser detection
Easy to use
Operates just by connecting to DC power supply
Circuit design optimized for detector element characteristics
Built-in thermoelectric cooling control circuit (fixed control
