Product description

There are many materials in the vacuum coating industry that cannot be evaporated by resistive heating, such as insulating materials commonly used for coating visible and near-infrared optics. In this case, electron beam heating must be used.
The source of evaporation for electron beam heating is an electron gun. The cathode material is usually molybdenum and is used in pairs, often referred to as left and right cathodes.
Molybdenum ASTM B387
