This is general product manufactured by continuous drawing .
after drawing, the tubes are treated by baking for OH contents control for mercury lamp,halogen lamp and other
applications.Electric heater, semiconductor materials, optical fiber parts .
The translucent quartz tube(NC-U100 series) can be made by this method and used for ultrared lamp application.
