FlashPoint_Crystals_300FlashPont carry's a wide range of scintillator crystals, casings, optical glass and sizes suited to specific environmental operating conditions, and gamma ray energy emissions for the medical, homeland security, downhole tool, measurement while drilling (MWD) and low energy physics sectors.

Selection of the correct crystal and the correct materials used for the scintillators casing, optical window, and internal expansion technology will be critical to the long term success of these units. 

Although FlashPoint may not carry all of scintillator crystal types, consider these features when selecting the correct scintillator for your application:
