ABSTRACT:
An ultraviolet radiation projector of this invention includes a focusing optical member arranged between an exposure surface of an ultraviolet sensitive material and a panel surface of a CRT for emitting an ultraviolet beam to expose the exposure surface which is kept separated from the focusing optical member, thereby preventing contact between the exposure surface and the focusing optical member. An optical image forming apparatus of this invention can form a high-precision two-dimensional image for an electronic circuit pattern by exposing the exposure surface with a pattern corresponding to a desired electronic circuit pattern using the ultraviolet radiation projector as a light source. In addition, sheet-like resins cured by the exposure with the ultraviolet beam using the ultraviolet radiation projector as a light source are sequentially stacked to form a desired high-precision three-dimensional image.
