    • An optical fiber coupling system is provided which minimizes beam loss. The system includes a substrate with a laser beam emitting unit attached at one end, a first fine lens which focuses or collimates a vertical beam emitted by the laser beam emitting unit, a set of second fine lenses which focus or collimate a horizontal beam emitted by the laser beam emitting unit, and a beam output unit which outputs the beam focused or collimated by the first and second fine lenses. This arrangement reduces an alignment error associated with this type of optical system and improves a degree of beam focus. Additionally, the optical fiber coupling system can be made compact and available for mass-production.

    • Disclosed is an appearance processing method comprising: designing a reference appearance for designing a set shape as a theoretical value; producing a specimen; comparing the reference appearance with the specimen and thus setting a deviation region; performing ion beam milling for milling the deviation region of the specimen by ion beam; and comparing the milling-processed specimen with the reference appearance after the ion beam milling thus to obtain a deviation and milling the deviation region repeatedly thus to make the specimen consist with the reference appearance. Accordingly, an arbitrary shape, a minute spherical surface, or an aspheric shape can be precisely processed, and a large quantity of fabrication by a uniform processing precision is possible.

    • Disclosed herein are a microlens array sheet and a manufacturing method thereof. The microlens array sheet comprises: a transparent substrate to be arrayed with microlenses; bases formed on the transparent substrate to a height determined by a user, the bases being formed at the same positions as microlenses to be formed later; microlenses formed on the bases; and a gap-filling film applied on the resulting structure, in which the bases have the same height as a result of a planarization process conducted for the upper portion of the bases. The method comprises the steps of: (a) depositing base-forming molds having a shape and thickness desired by a user on a transparent support substrate or film and loading a material to be used as bases between the base-forming molds; (b) polishing the upper portion of the material for use as bases so as to form bases having the same level and removing the base-forming molds; (c) depositing microlenses on the formed bases; and (d) depositing a gap-filling film on the resulting structure.
