Thallium doped Sodium Iodide Scintillation Crystals
We offer high quality NaI(Tl) scintillation crystals of various shapes and sizes as well as pixelated arrays. We have full capability to cut, shape, polish and coat the crystals as well as couple with silicone photodiodes in order to meet your specific requirements.
Thallium doped Sodium Iodide - NaI(Tl)
NaI(Tl) - Thallium doped Sodium Iodide is the most commonly used scintillation crystal. NaI(Tl) is one of the brightest scintillators available surpassed only by our GAGG(Ce) scintillator. NaI(Tl) has a high level of optical output and marginal self-absorption of scintillation light.
NaI(Tl) is highly hygroscopic. Contact with water and humidity should be avoided and encapsulation (container) is required.
