Basic profile of the enterprise: Rooted in the industrial highland, complete qualifications lay a solid foundation
Hubei Sanhai Optics Co., Ltd. was established on March 20, 2025. It is a high-tech enterprise focusing on high-end optical core components. The legal representative is Wang Yashi, with a registered capital of 20 million yuan. The registered address is located in Wuhan Iron and Steel Cloud Valley · Intelligent Manufacturing Park (Buildings A10 and A11), Hongshan District, Wuhan City, Hubei Province. This park is a key carrier of the intelligent manufacturing industrial cluster that Wuhan is focusing on building. It is adjacent to the Optics Valley Optoelectronic Information Industry Belt and shares public technical service platforms such as optical inspection and precision processing, with significant industrial synergy advantages. The company's unified social credit code is 91420111MAED9K9B52. It passed the ISO9001 quality management system certification and was included in the high-tech enterprise cultivation database in the year of its establishment. In 2026, it was officially recognized as a high-tech enterprise in Hubei Province. It simultaneously holds two utility model patents, namely "Precision Optical Component Coating" and "Grating Ruler Lithography Process", as well as three software Copyrights. The company currently has 86 employees, among whom 35% are in the R&D team. The core technical personnel all have over 10 years of experience in the high-end optical industry and come from well-known enterprises and universities such as Sunny Optical, O-film, and the School of Optics and Electronic Information of Huazhong University of Science and Technology, forming a composite R&D team of "precision manufacturing + optical design + system integration".

The company’s core team boasts over 20‑years of in‑depth experience in the optics industry, with solid technical accumulation and strong innovative R&D capabilities, and has built a solid product reputation across the sector. It operates a 3,600‑square‑meter modern production facility equipped with Class‑100 and Class‑1000 clean‑rooms. Imported precision processing equipment and full‑spectrum inspection systems from Japan and Germany have been deployed. The company has established a full‑industrial‑chain workflow covering raw‑material cutting, precision machining, optical coating and photolithography manufacturing, enabling nanometer‑level processing accuracy and delivering high‑quality optical solutions for customers.

The company runs three business divisions: Intelligent Sensing, Optical Communications and Automotive. The Intelligent Sensing Division focuses on core optical components for industrial automation, mainly offering high‑precision grating encoders, grating scales, calibration plates and reticles. The Optical Communications Division specializes in optical‑communication components including silicon lenses, C‑Lens, Z‑Block and heat‑resistant substrates. The Automotive Division is dedicated to LiDAR for intelligent driving, supplying metal code discs, narrow‑band filters, reflectors, vehicle logos, window sheets and various coated automotive‑optical devices. Its products serve high‑end application scenarios such as precision control for industrial automation, semiconductor equipment, intelligent driving, robotics, laser equipment, security surveillance, medical instruments and aerospace.

Core positioning and business matrix: Focusing on high-end substitution, covering the entire industrial chain services
Sanhai Optics takes "breaking the reliance on imported high-end optical devices and empowering the upgrading of strategic emerging industries" as its core positioning, and builds a full industrial chain business model of "R&D and design - core manufacturing - customized services - terminal support". Its core business covers three major sectors, and each sector forms a clear market stratification and synergy effect: High-end optical component manufacturing (core business) : Focusing on nanometer-level precision optical core components, covering code disks, grating rulers, lens groups, filters, etc., it mainly provides core components for encoder and precision measuring instrument manufacturers, replacing the mid-to-high-end product lines of imported brands (such as Heidenhain and Keyence). Currently, its market share in the domestic robot encoder optical code disk market has reached 8%. Optical communication and automotive optical Components (Growth Business) : Focusing on 5G communication base stations and intelligent driving fields, we develop and produce coupling lenses for 100G optical modules, automotive lidar receiving lenses, and optical components for ADAS cameras. We have entered the supplier systems of Huawei hisilicon and Desay SV. By 2026, the revenue share of this segment is expected to reach 32%. Customized optical system solutions (strategic business) : For special fields such as medical and aerospace, we provide an integrated service of "optical design - sample trial production - small batch production". For example, the minimally invasive surgical endoscope optical system customized for a certain medical equipment enterprise has improved the imaging resolution to 1080P@60fps and has been applied in clinical trials in a tertiary hospital.
