LEYBOLD OPTICS Application Update in R2R Vacuum Coating

摘要

1. Improved setup of gun parameter, e.g. high-/acceleration voltage, for higher efficiency at lower emission current; 2. Optimized dimensioning of the heating transformer using a lower range of emission current, for more accurate and stable control of the emission current; 3. Simplified adjustment of gun parameter using potentiometer implemented in the operation desk.
