Base

The two diametrically opposed cylindrical extensions, or bases, serve to mechanically support the mercury xenon lamps during system installation, as well as to provide a means for electrical connection. Inside the ferrule, or base, is a flexible lead wire that eliminates any possibility of stress or strain between the electrode shaft and the ferrule. The ferrules are attached to the quartz envelope using a unique carbon-graphite tape and passivated compression ring. For installation, the ferrules have non-threaded pins and a cable. All of LTI’s ferrules are nickel-plated to ensure good electrical contact, thermal contact, and to prevent oxidation. The ferrules have polarity cutouts to assist in installation and to facilitate cooling.
