INFRARED DETECTOR

Infrared detector module with preamp

Non-cooled Type

Easy-to-use detector module with built-in preamp

These Infrared detector modules with preamp are designed to operate at room temperatures by just connecting to a DC power supply. The
detector element is selectable from among InGaAs, PbSe and Ge. B7506-01 detector is especially suited for CO
requests for custom devices that suit your application.
