Selection guide | Photomultiplier tubes (PMTs)

Vacuum ultraviolet (VUV) to ultraviolet (UV)

These photomultiplier tubes have high sensitivity in the ultraviolet region.
When selecting a photomultiplier tube it is essential to select a light input window made from glass material that passes ultraviolet light.

Topics


Solar-blind characteristics

Photomultiplier tubes with so-called ’solar-blind‘ characteristics have little sensitivity to wavelengths longer than 200 to 300 nm and so are mainly used for VUV to UV measurements in vacuum environments. Their window materials are MgF2 crystals and quartz glass.

Radiation measurement

The photomultiplier tube and NaI (sodium iodide) scintillator combination is one of the most common techniques for radiation measurement. Photomultiplier tubes with a semi-transparent photocathode are widely used since their sensitivity matches the emission spectrum of NaI scintillators near the 420 nm light wavelength. Some semi-transparent photocathodes can provide enhanced sensitivity on long wavelengths by minor modifications to the fabrication process.

InGaAs (indium gallium arsenide) photocathode

The InGaAs photocathode is a crystalline photocathode the same as GaAsP. However, unlike the GaAsP photocathode with its high sensitivity to visible light, the InGaAs photocathode can detect near-infrared light from 950 to 1700 nm.
