As aspheric lenses have become more common, don't you think they are still a bit out of reach? Our company can accommodate orders starting from just one piece.
This is an aspherical lens from a glass material supplier who knows the materials inside and out. We have over 30 years of supply experience. Taking advantage of the flexibility typical of small and medium-sized enterprises, we can accommodate small lots starting from just one piece. While aspherical lenses have become quite common and are often seen, when you actually place an order, you may find that suppliers are unwilling to accept small quantities or that the prices are too high. Do you want to reduce costs on aspherical lenses after prototyping with catalog products, or do you have custom requests? Please feel free to contact us at [Sumida Optical Glass].

Company information
Japan is one of the world's leading producers of optical equipment, with optical glass being a key component. Since its establishment in 1953, SUMITA has been engaged in the world of light and glass as one of the few expert companies in this field. Since the 1960s, we have pursued our unique optical fiber technology. Additionally, we maintain a consistent production process from raw materials to final products, and there are very few companies globally that can mass-produce glass optical fibers at a scale of up to 700,000 km per month. We have earned high trust not only in the domestic market but also in overseas markets. Our optical fiber materials offer excellent cost performance and are applied in a wide range of fields, including medical devices, telecommunications, image processing, measurement, sensors, and lighting.
