Home > Scintillating Crystals
Scintillating Crystals are used to detect the energy and intensity level of Y or X ray and provide high luminous efficiency. These crystals have been playing an important role in security inspection and detection devices in various occasions, such as airport, railway station, custom port as well as oil field and geographic exploration. MTI supplies high quality scintillation crystals, mainly CdWO4, CsI(Tl) and Ce:YAG etc. at the most competitive price to meet customer's every demand. We usually don't keep the scintillation crystal components in stock. If you have any need, please let us know size, polished face, crystal orientation and quantity, we will reply you within 24 hours
