Abstract

We have developed industrial technique to produce plastic rod-lens and its linear array. The basic characteristics of the rod-lens was revealed. The optical resolution was 200dpi which was high enough to apply to G3-facsimile and monochromatic copy machine. 300dpi or 400dpi optical resolution is required for the application to G4-facsimile and image scanner of computer, LED printer and so on. Two approach to improve the optical resolution were proposed and discussed those method form the practical view point of durability in the linear rod-lens array. Finally the total characteristic of the plastic rod-lens were compared with that of glass material.
