Abstract: The present invention relates to an ignition device for igniting a high-current discharge of an electrical arc evaporator in a vacuum coating system. Ignition is performed by means of mechanically closing and opening a contact between the cathode and the anode. Contact is established by means of an ignition finger that can move on a forced path. On account of the forced path, the ignition finger can be moved by means of a simple mechanical drive to a park position, which is protected against coating, and said ignition finger can also be used to ignite a second target.

Abstract: A pressure sensitive adhesive (PSA) is used to attach a plurality of wedge-shaped glass filter segments on a first side to a hub during the color ring build portion of the color wheel fabrication process. A strong adhesive, such as epoxy, is then used to adhere a second side of the filter segments directly to a turning surface of a motor, completing the color wheel fabrication. The epoxy is cured if necessary. The pressure sensitive adhesive can temporarily align the plurality of color filter segments in an alignment. The adhesive between the filter segments and the turning surface can then permanently bond the color filter segments in the alignment.
