The distortion of the wavefront achieved an excellent polishing precision of 0.26μm! We have successfully processed the polishing of LBO single crystal substrates.
This is an introduction to the polishing processing results of the "large LBO single crystal substrate" (100×100×1.5mm). The disturbance of the transmitted wavefront achieves an excellent polishing accuracy of 0.26μm. We have successfully polished the LBO single crystal substrate, which is used in the LFEX laser. 【Overview】 ■ Shape accuracy: PV0.26μm, Measurement device: Zygo Verifire ATZ ■ Surface roughness: Sa0.44nm, Measurement device: Zygo NewView 8300 ■ Substrate size: 100×100×1.5mm *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.
