Different approaches were studied for welded butt observing in the vacuum chambers under conditions of intensive deposition. The results of development of new optical system suitable for application in industrially applied guns of ELA 60/60 type are given. The system differs by simplicity and possibility of wide application of standard assemblies. The system will find commercial application due to completeness of set, high functionality and simplicity. 3 Ref., 6 Figures. K e y w o r d s :
