Consistent production from prototype to mass production through innovative technology.
Product Introduction: Glass Molded Lenses Glass molded lenses, created through die-casting molding, achieve complex shapes that are difficult to produce through polishing and lens structures that previously required assembly, all in a single molding process. Most products are fully customized according to customer requests, with flexible support from prototyping to mass production. In addition to the lens molding technology developed over many years, we utilize unique measurement and inspection techniques to provide high-precision products. We cater to a variety of shapes and specifications, including not only lens arrays but also aspherical lenses, Fresnel lenses, rod lenses, and irregularly shaped lenses. Features ■ Integrated glass lenses through molding ■ Achieves complex shapes and integrated structures, enabling shapes that are difficult to polish ■ Supports prototyping to mass production with full customization ■ Proven track record with various shapes including aspherical lenses, Fresnel lenses, rod lenses, and irregularly shaped lenses ■ Guarantees high quality with unique measurement and inspection technologies
