Technology for Development Fiber Optics and Radiation Sensitive
Light-guide for Ecology and Medicine
 

Purpose:

With the help of new technology unique infrared crystals on the basis of solid solutions of silver halogenides are received. They are used for production of a new class of halogenidesilver crystal scintillators and fibre optics.
