Our company's original development! Introduction to ultra-precision aspheric lens processing technology.
Our uniquely developed polishing technology has made ultra-precision polishing of aspherical surfaces possible.
This is an introduction to the processing of aspherical lenses in crystal optics. Until now, we have primarily focused on the production of glass spherical lenses. With our unique polishing technology, we have made it possible to manufacture aspherical lenses. As a result, we can offer a complete in-house process from the procurement of glass materials for aspherical lenses to finishing and polishing. The lenses we produce are utilized in various fields, including space and astronomy. 【Product Example】 ■ Aspherical Cylindrical Lens Surface Shape: Cylindrical Surface + Flat Surface * Cylinder Surface Accuracy (after intermediate polishing) * Cylinder Surface Accuracy (after finishing polishing) Shape Accuracy: 0.6μm PV Shape Accuracy: 0.0027μm PV Surface Roughness: 3nm Sa Surface Roughness: 0.756nm Sa We can also polish aspherical shapes of other special shapes and materials. We can accommodate small lots and prototypes as well. * For more details, please feel free to contact us through our website. https://www.crystal-opt.co.jp/

Company information
Our company, at the time of its founding, was engaged in the hand polishing of optical single crystals. Among optical crystal materials, there are extremely delicate materials that can only be polished in environments with strict control of temperature and humidity. Based on this polishing technology, we have been involved in the polishing of various materials up to the present day. Now, after 30 years, we have expanded our capabilities to handle not only single crystals but also all kinds of materials including metals, non-metals, and ceramics. Initially, we processed small components that could fit in the palm of a hand, but today we are capable of handling ultra-large components up to 8000mm. In terms of our business (processing), we are focusing on in-house integrated production to achieve higher precision processing. We have established six fields: cutting, grinding, polishing, ultra-precision processing, surface treatment (non-conductive treatment/electropolishing), and measurement, allowing our customers to provide just one drawing and entrust all processing to us. In November 2014, with the aim of engaging in the aerospace industry, we introduced two new 5-axis composite machining centers, and we will do our utmost to contribute to the aerospace industry, which promotes the evolution of space.
