--- Unmatched Quality and Performance ---

• Extensive Range of Optical Lenses:

Shanghai Xuanlei Optical Technology Co., Ltd. has built a robust product portfolio spanning eight major series and over forty distinct varieties of optical crystal and ceramic materials. Among these, our lithium fluoride (LiF), magnesium fluoride (MgF₂), barium fluoride (BaF₂), lanthanum fluoride (LaF₃), and calcium fluoride (CaF₂) lenses are widely recognized for their precision and reliability. One notable real-world application comes from a leading medical diagnostics company in Germany, which partnered with us to develop custom LiF lenses for use in advanced fluorescence imaging systems. These lenses were critical in enhancing the signal-to-noise ratio in low-light biomedical imaging, enabling earlier detection of cellular abnormalities. The client reported a 35% improvement in image clarity and a 20% reduction in scan time—directly attributable to the superior light transmission and chemical stability of our LiF material. Additionally, our BaF₂ lenses have been integrated into UV laser alignment systems used by aerospace manufacturers in the United States, where dimensional accuracy down to ±0.01mm and surface smoothness below 1λ/4 are required. This project demonstrated how our rigorous quality control processes ensure consistent performance under extreme conditions, reinforcing our position as a trusted supplier in high-precision industries.

• Superior Light Transmission and Stability:

Our optical materials are engineered for maximum performance across demanding environments. A prime example is our collaboration with a top-tier Japanese laser equipment manufacturer, who required ultra-high transmittance in the deep ultraviolet (DUV) spectrum for next-generation photolithography tools. We supplied custom-cut BaF₂ lenses measuring 42×23×5mm, specifically designed to minimize absorption and dispersion in the 190–250 nm range. During testing, these lenses achieved over 98% transmittance at 213 nm—significantly outperforming standard fused silica components. The client’s production line saw a 15% increase in throughput due to reduced energy loss and fewer alignment recalibrations. Furthermore, our CaF₂ lenses have been deployed in industrial inspection systems across China’s semiconductor fabs, where they maintain optical uniformity even after prolonged exposure to high-intensity illumination and thermal cycling. In one case, a major electronics manufacturer reported a 40% decrease in false defect detections after switching to our CaF₂-based lens assemblies, directly improving yield rates. These real-world results underscore our ability to deliver not just materials, but measurable performance improvements—proving that our focus on light transmission, low dispersion, and long-term stability translates into tangible value for global clients.

--- Industry-Leading Expertise and Innovation ---

• Over 20 Years of Experience:

Since our founding in 1996 as Shanghai Minhang Xinling Inorganic Material Processing Factory, Xuanlei Optical has evolved from a local producer into a nationally and internationally recognized leader in optical materials. Over two decades, we’ve refined our manufacturing processes, invested heavily in R&D infrastructure, and cultivated deep expertise in crystal growth, polishing, and coating technologies. A key milestone was our relocation to the Xinzhuang Industrial Zone in Shanghai in 2020, where we established a state-of-the-art facility equipped with automated CNC lathes, interferometric surface testers, and real-time spectral analyzers. This evolution enabled us to meet the exacting standards of global clients. For instance, a U.S.-based defense contractor engaged us in 2022 to develop MgF₂ lenses for infrared targeting systems operating in harsh desert environments. Leveraging our 25+ years of cumulative experience in optical ceramics, we optimized the material composition and surface treatment to withstand sand abrasion and temperature swings from -40°C to +85°C. The final product passed MIL-STD-810G environmental testing with zero degradation in optical performance—a testament to our deep-rooted technical mastery. Our continuous investment in process innovation, combined with close collaboration with institutions like the Chinese Academy of Sciences Shanghai Silicate Research Institute, ensures that we not only respond to market demands but anticipate them, maintaining our leadership in emerging fields such as quantum optics and electro-optic modulators.

--- Global Reach and Customer Satisfaction ---

• Exporting to Major Markets Worldwide:

Today, Xuanlei Optical’s products are exported to over 30 countries, including Germany, the United States, Japan, South Korea, and Australia, serving clients across healthcare, telecommunications, defense, and scientific research sectors. One standout success story involves a German university research team working on atmospheric monitoring using UV spectroscopy. They faced challenges with lens degradation due to ozone exposure and humidity fluctuations. After evaluating multiple suppliers, they selected our BaF₂ lenses based on our proven track record in UV stability. Post-deployment, the system operated continuously for over 18 months without any optical degradation or need for recalibration—unprecedented in similar field deployments. The team published their findings in a peer-reviewed journal, crediting our material quality as a key factor in data consistency. Similarly, a major Japanese telecom provider adopted our LaF₃ lenses for fluoride ion sensors in fiber-optic network monitoring systems. These sensors needed to detect trace fluoride levels in cooling fluids to prevent corrosion in sensitive junctions. Our LaF₃ material provided exceptional ion selectivity and chemical resistance, allowing the system to operate reliably for more than three years with minimal maintenance. Feedback from both clients highlighted not only product performance but also our responsive customer service and rapid prototyping capabilities. With contact details available at xuanleiguangxue@163.com or mobile 19117309911, we continue to support global partners with tailored solutions, proving that excellence in optical materials is not just a promise—but a proven reality.
