DH_30_TE Cooled Multi-Alkali Photomultiplier (200-900nm)

  • DH_30_TE detector 200-900nm

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. Peltier elements, powered by the CPS1/CPS1M ensure temperature control.

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 quick-change mounting flange supplied with the DH_30_TE is compatible with the entire range of Bentham monochromators and accessories.
