Manufactured a large-diameter high-precision glass mirror with a rib structure aimed at weight reduction and spherical processing.
We would like to introduce our processing achievements of "large-diameter lightweight glass mirrors" for satellite mounting. In space, various artificial satellites are flying, equipped with numerous precision optical components such as mirrors and lenses. Our company has manufactured large-diameter, high-precision glass mirrors with a rib structure (on the back) for weight reduction and spherical processing (on the front). Additionally, we installed a unit on a large three-dimensional measuring machine (MMZ) and were involved in the alignment of multiple mirrors. 【Overview】 ■ Shape accuracy: PV 212.562nm ■ RMS: 19.906nm ■ Measuring machine: Zygo Verifire ATZ ■ Measuring equipment used: - Large-diameter (12-inch) laser interferometer - Ultra-large three-dimensional coordinate measuring machine *For more details, please refer to the PDF document or feel free to contact us.

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.
