MIRROR FOR LIGHT SCANNING UNIT AND MEHTOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A mirror for light scanning unit and method of manufacturing the same are provided to reduce the fabrication time by reducing the thickness of the protective layer. CONSTITUTION: The mirror for the optical scanning apparatus comprises the epoxy(210), the silver layer(220), and the protective layer(230) and MgO layer(225). The silver layer is formed in epoxy. The protective layer is formed on the top of the silver layer. The MgO layer is formed between the silver layer and protective layer. The bonding layer(212) is formed between epoxy and silver layer. The bonding layer is formed in order to increase the adhesive force between epoxy and the silver layer. The bonding layer is formed on the top of epoxy with the sputtering method by evaporating Ti to the prescribed thickness. The thickness of bonding layer is approximately 50~100Å. The MgO layer increases the adhesive force between the protective layer and the silver layer.
