DH_30 Multi-Alkali Photomultiplier

The DH_30 photomultiplier is a cost-effective solution for low-light UV-vis applications. 

Incorporating a multi-alkali photomultiplier tube (S20 photocathode) with side window, mu-metal shielding and a PCB-based dynode chain, reliable operation can be assured. The high-voltage power supply module 215 maintains the photocathode at a high negative voltage. The photocurrent generated by this detector is best measured using the 487 picoameter or the 477 preamplifier followed by the 496 lock-in amplifier. 

The mounting flange supplied with the DH_30 is compatible with the full range of Bentham monochromators and accessories.
