Pure Cesium Iodide Scintillation Crystals
We offer high quality CsI(Pure) 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.
Pure Cesium Iodide - CsI(Pure)
CsI(Pure) - Pure Cesium Iodide has an emission wavelength of 315nm and a very fast decay time of 16ns. CsI(Pure) has a light yield of 2 photons/KeV and very good stopping power due to its high density and atomic number. Light output of CsI(Pure) scintillators at room temprature is low, but increases at lower tempratures. The same low tempratures increase the decay time making it slower.
CsI(Pure) is slightly hygroscopic. Contact with water and humidity should be avoided.
