Abstract

PURPOSE:To inexpensively form a firm conductive layer on an optical lens by ion- plating the conductive layer on the lens with the mesh mounted to the optical lens of the projection type Braun tube as an electrode. CONSTITUTION:Inert gas such as Ar is introduced by evacuating the inside of a bell-jar 9. Current is supplied to a vapor source 6 to allow In to evaporate. The evaporated In are ionized while colliding against Ar molecules and are accelerated to an ion flow 10 by the electric field formed by the high voltage applied to a mesh electrode 4. This ion current impinges upon a meniscus lens 1. At this time, the plating film assumes the patterns corresponding to the mesh patterns but the In ions also go to the back side of the mesh and therefore it becomes the conductive film having considerable continuity, and this provides the conductive layer having a sufficient function as an optical lens. Also, the In permeates into the surface of the lens 1, thus the firm conductive layers is formed.
