DH_IGA Photodiode (800-1700nm)

  • DH_IGA photodiode 800nm-1700nm
  • DH_IGA detector
  • DH_IGA detector with quick change adaptor
  • DH_IGA detector with quick change interface

Housing a 3mm diameter active area InGaAs photodiode (800-1700nm), the DH_IGA 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_IGA is compatible with the entire range of Bentham monochromators and accessories. A quick-change variant is also available. Other options include thermoelectric cooling for ultimate stability (yet reduced spectral range), and a lensed solution to maximise coupling from monochromator.
