SDYY Precision Lens Technology Corporation is one of the leading Fresnel lens production and supply enterprises in China.
We provide different types of Fresnel lenses for thousands of customers worldwide (3M, Philips, Siemens, Midea, etc.).
In 2000, we developed and produced reflective Fresnel lenses and built a new clean and dust-free workshop
In 2002, Injection mold construction workshop was established and human body sensing infrared lens was developed and produced, entering the LCD projector market
In 2004, we independently designed, developed and produced infrared human body sensing lenses.
In 2008, a photovoltaic lens research and development team was established, and PMMA array photovoltaic lens and silicon gel toughened glass lens were developed
In 2011, four condensing photovoltaic lens production workshops were put into use, with a daily production volume of over 3000 square meters. Becoming a major supplier of condensing photovoltaic lenses both domestically and internationally.
In 2015, the task of completing 120 sets of infrared lens molds for the entire year was successfully completed, and the sales volume of infrared lenses reached 50 million, further expanding market share and brand influence.
In 2016, the performance of lenses was diversified, and Fresnel lenses were used for various purposes in various fields such as artificial intelligence, LCD projection, LED lighting distribution, and concentrated light and heat collection. And collaborate with companies such as Philips, Siemens, and Goertek to develop new lenses.
In 2018, nearly 100 million human infrared sensing lenses were produced and sold.
In 2019, we developed innovative applications of Fresnel lenses in smart homes, security, LED lighting, and other fields.

Since its establishment, the company has been focusing on the research and production of Fresnel lenses. With a professional R&D team of Fresnel lenses and a sales team of hundreds of high-precision equipment specializing in the production of Fresnel lenses, we provide Fresnel lenses for different purposes to thousands of customers (3M, Philips, Siemens, Panasonic, LGcDisplay, Hikvision, Dahua,Midea…) both domestically and internationally.
Fresnel lenses are mainly used in the optical imaging industry (projectors, projectors, VR, AR, etc.). Fresnel lenses are used for LED lighting distribution (spotlights, projectors, stage lights, traffic signals, etc.), infrared induction lenses are used for (Industry 4.0 intelligent fields, building security systems, induction lighting, etc.), and large Fresnel lenses are used for (photovoltaic concentrating power generation, heat collection, light utilization, etc.).
