For more than two decades, we have remained dedicated to the research, development, and manufacturing of optical products. We have gradually established production bases at Tianhuo Songlin Optics (Guangzhou) Co., Ltd. and Songlin Optoelectronic Technology (Hubei) Co., Ltd., forming a comprehensive production portfolio that covers prisms, lenses, plane mirrors, optical lenses, and optical components. As a high-tech enterprise and a “Little Giant” enterprise recognized under the Specialized, Refined, Distinctive, and Innovative program, we utilize high-precision equipment to achieve micron-level machining. Leveraging leading manufacturing and high-precision measurement technologies, and operating under a comprehensive quality management system that spans from source to end product, we translate our technical expertise into every high-quality, reliable optical product. Our optical products are widely used in multiple critical fields: from color reproduction in projectors to crisp imagery in laser TVs; from microscopic insights in microscopes to sensitive detection in industrial lenses; from safety features in in-vehicle HUDs to precise authentication in biometrics. We also provide in-depth support for cutting-edge fields such as AR/VR, 3D scanning and printing, inspection equipment, and thermal imaging systems. We possess the capability to undertake ODM and OEM projects for projection lenses, industrial lenses, zoom lenses, far-infrared lenses, line-scan lenses, and other types of optical lenses. In the eyes of renowned domestic and international brand clients, we are a reliable partner in precision optical manufacturing who “understands optics and customer needs.” We look forward to joining forces with outstanding talent from around the world to build on our legacy and forge ahead, ensuring that optical technology remains at the forefront of industry applications, continuously empowering industrial progress, and serving as a key driver of high-quality development.
