Zhongshan Union Optech, as a world-leading supplier of precision optical solutions, has been deeply engaged in the mobile phone optical field for more than 20 years. Relying on its independently developed three core technologies—high-definition pixels, variable aperture, and optical image stabilization (OIS)—Union Optech has built a strong technological barrier. On this basis, its differentiated advantages such as stable long-distance/macro imaging capabilities, mass production capabilities of fixed-focus lenses for medium focal lengths, and customized development capabilities of periscope telephoto lenses have been fully exerted, enabling it to provide comprehensive, one-stop mobile phone camera solutions for smartphone manufacturers.
