Scintillation Crystals
We offer high quality CsI(Tl), CsI(Na), CsI(Pure), NaI(Tl) and GAGG(Ce) 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.
• CsI(Tl) - Thallium activated Cesium IodideCsI(Tl) - Thallium activated Cesium Iodide, is one of the brightest available scintillators which has very good stopping power and is physically rugged. Read more...
• CsI(Na) - Sodium doped Cesium IodideCsI(Na) - Sodium doped Cesium Iodide, is a bright scintillator which has very good stopping power and a fast decay time. Its mechanical properties make it highly suitable for work in harsh conditions. Read more...
• CsI(Pure) - Pure Cesium IodideCsI(Pure) - Pure Cesium Iodide, is a very fast scintillator with high stopping power. CsI(Pure) has a light yield of 2 photons/KeV and an emission wavelength of 315nm. Read more...
• NaI(Tl) - Thallium doped Sodium IodideNaI(Tl) - Thallium doped Sodium Iodide, is the most commonly used scintillator. NaI(Tl) has a high level of optical output and marginal self-absorption of scintillation light. Read more...
• GAGG(Ce) - Cerium doped Gadolinium Aluminium Gallium GarnetGAGG(Ce) is a new type of high performance single crystal scintillator. It is one of the brightest available scintillators with high performance properties. Read more... |
