Housing a 5mm diameter active area germanium photodiode (800-1800nm), the DH_Ge is operated in the photovoltaic mode. The photocurrent generated by this detector is best measured using the 487 picoammeter or the 477 pre-amplifier followed by the 496 lock-in amplifier.

The mounting flange supplied with the DH_Ge is compatible with the entire range of Bentham monochromators and accessories.
