Often taken for granted or misunderstood, the scintillator is a fundamental component of your microscope. The scintillator is responsible for converting the electrons that are collected from the sample into photons. Essentially, a scintillator is a phosphor coating deposited onto a substrate. Some scintillators are composed of a single crystal alone. We have been manufacturing and recoating the finest in scintillators since 1972.

Signal-to-noise ratio, brightness and longevity are the most critical measures of scintillator quality. At one time, response time was considered an issue but today virtually all commercially available scintillators have adequate response time for a SEM (less than 100 ns.) The smoothness of the surface and the conductivity determines the signal-to-noise ratio. When new, almost any SEM scintillator will give sufficient brightness to obtain adequate images, however, different types of scintillators lose their brightness at different rates.

We offer P47 (medium lifetime, good brightness), Pilot B (short lifetime, medium brightness), YAP:Ce or YAG:Ce (long lifetime, medium brightness), and our new LXSR scintillators (long lifetime, excellent brightness).

The overall performance of P47P as measured by brightness, cost and match to PMT range and sensitivity make it the scintillator of choice for most applications. Plastic scintillators (Pilot B) have the shortest life. All scintillators have a shortened life with surface contamination from the SEM. A few can be factory cleaned like YAP:Ce, YAG:Ce and LXSR.
