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
2
laser detection. We welcome
requests for custom devices that suit your application.
