Sanhai Optics Secures Exclusive Angel Round Funding to Accelerate Layout in High-End Optical Components
Recently, Hongshan Capital completed an exclusive angel round investment in Hubei Sanhai Optics Co., Ltd. (hereinafter referred to as "Sanhai Optics"). The funds will be mainly used to advance mass production and delivery of products, and facilitate the implementation of the company’s business plan. Backed by this investment, Sanhai Optics will establish its corporate headquarters in Hongshan District and construct a nearly 3,000-square-meter production base at Wugang Yungu 606 Industrial Park in Hongshan District, building a complete industrial chain production capacity covering "precision machining, coating, and lithography." This move will help "supplement and strengthen the regional optoelectronic industrial chain."
Founded in March 2025, Sanhai Optics is jointly initiated by leading talents in the optical components industry, a core team with rich experience in R&D, production, management, and marketing, as well as listed company Xiangyuan New Materials (Stock Code: 300980). The company’s business scope covers three major areas: manufacturing of optical instruments, manufacturing and sales of communication equipment, and manufacturing of optical communication equipment. Its product portfolio includes high-precision optical code discs, lenses, prisms, filters, and customized optical components, all boasting nano-level precision. These products are widely applied in high-end scenarios such as humanoid robots, automobiles, laser equipment, security monitoring, medical instruments, and aerospace.
Among them, optical code discs, as key components of encoders (core parts of servo motors), are in strong demand in fields such as robotics, industrial control, aerospace, medical care, and military industry. With the explosion of embodied intelligence and the humanoid robot industry, the market space for this product has further expanded. Taking Tesla’s Optimus humanoid robot as an example, a single unit requires over 50 encoders, corresponding to more than 50 optical code discs. In the humanoid robot track alone, the demand for optical code discs is expected to increase tenfold over the next decade.
Optical code discs are just Sanhai Optics’ "initial layout." Leveraging pan-semiconductor technologies such as lithography and coating, the company is accelerating the R&D of two core product lines: first, linear scales for high-end equipment such as precision machine tools (currently with extremely low localization rate); second, disruptive MEMS devices for wearable smart hardware such as AI glasses. The company continues to break through technical barriers in high-end optical components.
Thanks to its cutting-edge technologies and high-quality products, Sanhai Optics has become a supplier to several domestic and foreign leading enterprises within less than six months of its establishment. According to the company’s plan, it will serve 100 well-known global customers within one year and achieve a revenue of over RMB 100 million within three years.
In the future, Hongshan Capital will continue to adhere to its strategy of "investing early, investing in small enterprises, investing in hard technology, and investing for the long term," foster and expand patient capital, support frontier technological innovation, activate the industrial innovation engine with capital strength, and contribute to the development of key regional industrial clusters.
