The results of scientific and technological experiments performed in the Glass Department of Electronic Material Technology in Warsaw are presented. Research on fiber optic elements were carried out in areas of light guides made from multi component chalcogenide glass (Ge-Sb-Se). The laboratory methods of manufacturing the glass elements which are the starting for preparation of optimally material bathes and melting the glass in silica glass crucible. Method of pulling glass fibers for IR transmission was improved. Goal is to elaborate technology producing of IR fiber and ordered bundle for transferring pictures from inside human body without none additional illumination. Ability transmitting CO2 laser radiation by IR fiber optic may by simultaneously used as laser scalpel. Fiber optic made from chalcogenide glass is very promising.
