G6121 Datasheet, PDF (1/2 Pages) Hamamatsu Corporation – Infrared detector module with preamp

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 CO2 laser detection. We welcome
requests for custom devices that suit your application.
