Thallium activated Cesium Iodide Scintillation Crystals
We offer high quality CsI(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 activated Cesium Iodide - CsI(Tl)
CsI(Tl) - Thallium activated Cesium Iodide, is one of the brightest available scintillation crystals with an emission wavelength of 550nm. CsI(Tl) has a light yield of 54 photons/KeV and very good stopping power. CsI(Tl) is also physically rugged which makes it easy to handle and well suited for a broad range of applications including ones with severe shock conditions.
CsI(Tl) is slightly hygroscopic. Contact with water and humidity should be avoided.
