DH_30 Multi-Alkali Photomultiplier (200-850nm)

  • DH_30 detector 200-850nm

Housing a side-window multi-alkali (S20 photocathode) photomultiplier tube, a mu-metal shield and a PCB based dynode chain, reliable operation can be ensured. The 215 high voltage supply module maintains the photocathode at a negative high voltage. 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_30 is compatible with the entire range of Bentham monochromators and accessories.
