OHARA, propelled by its corporate DNA, the “pursuit of the highest quality”, we provide products and services that satisfy our customers and confidently develop and produce world-class new materials. Precision and homogeneity are the two characteristics most strictly required from optical and special glass. It means that their physical and optical properties must meet the design requirements and there must be no discrepancies among the same products.

All of the processes, including mixing of raw materials, cullet melting and preparation, continuous melting, pressing, cold working, annealing, product inspection, shipping and quality checks performed by internal staff and our partners across diverse production processes, have allowed us to develop management techniques that are among the best in the world. We focus our meticulous attention and efforts on maintaining and improving these techniques.
