DH_Si Silicon Photodiode (200-1100nm)

  • DH_SI Si detector 200-1100nm
  • DH_SI Si detector connector
  • DH_SI Si detector with quick change adaptor
  • DH_SI Si detector with quick change interface

Housing a 10x10mm active area silicon photodiode (200-1100nm), the DH_Si 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_Si is compatible with the entire range of Bentham monochromators and accessories. A quick-change variant is also available.
