Datasheet: R9110 Photomultiplier Tube

The R9110 photomultiplier tube (PMT) offers high sensitivity and low dark current for low-light measurements over a wide spectral range.

The R9110 is a 28 mm side-on PMT with a minimum effective area of 8 mm x 6 mm. Its spectral response range extends from 185 nm to 900 nm, with peak sensitivity at 450 nm. At this wavelength, the detector's multialkali photocathode has a radiant sensitivity of 90 mA/W and an extremely high quantum efficiency of 24.8%. Dark current is typically 5 nA after 30 minutes storage at room temperature.
