G6121_15 Datasheet, PDF (1/5 Pages) Hamamatsu Corporation – Infrared detector modules with preamps

Infrared detector modules with preamps
Non-cooled Type
Easy-to-use detector modules with built-in preamps
These infrared detector modules contain a preamp and operate by just connecting to a DC power supply. The detector element is
selectable from among InGaAs and PbSe detectors. Thermoelectrically cooled types are also available. Besides these detectors, we
welcome requests for custom devices that suit your application.
