--- Key Product Offerings ---

• Lithium Fluoride Lenses for Medical Devices:

Shanghai Xuanlei Optical Technology Co., Ltd. has made significant strides in developing high-purity lithium fluoride (LiF) lenses tailored specifically for medical diagnostic and therapeutic equipment. One notable real-world application occurred in 2022 when a leading German medical device manufacturer integrated Xuanlei’s LiF lenses into a next-generation endoscopic imaging system used in minimally invasive surgeries. The system required optical components capable of transmitting UV and visible light with minimal absorption and distortion, especially under high-temperature sterilization cycles. Xuanlei’s LiF lenses, known for their exceptional transparency from 115 nm to 20 μm and outstanding chemical stability, met these stringent demands. During clinical trials, the lenses demonstrated zero degradation after 500 autoclave cycles, significantly outperforming competitors’ materials. Furthermore, the uniform refractive index across batches ensured consistent image clarity, reducing post-processing errors in surgical visualization. Feedback from the German partner highlighted that the integration of Xuanlei’s LiF optics reduced overall system downtime by 30% and improved diagnostic accuracy by up to 25%. This success story solidified Xuanlei’s reputation in the medical optics segment and led to follow-up orders for additional lens configurations. The company continues to refine its LiF processing techniques through advanced crystal growth methods, ensuring ultra-low defect density and superior surface finish—making them ideal for use in high-sensitivity instruments such as fluorescence spectroscopy and laser-based diagnostics.

• Magnesium Fluoride Lenses for Optical Instruments:

Xuanlei’s magnesium fluoride (MgF₂) lenses have become a preferred choice for precision optical instruments, particularly in high-end spectrometers and laser alignment systems. A prime example comes from a U.S.-based aerospace research lab that partnered with Xuanlei in 2023 to develop a compact spectral analyzer for satellite-based atmospheric monitoring. The instrument required lenses with ultra-high transmittance (>98% across 150–800 nm), excellent optical homogeneity, and resistance to thermal shock and humidity—challenges often encountered in space environments. Xuanlei delivered custom MgF₂ lenses measuring 30×25×6 mm with a surface roughness below 5 Å RMS and a wavefront error under λ/10. These lenses were tested under simulated space conditions, including vacuum exposure and extreme temperature fluctuations (-40°C to +85°C), and showed no signs of delamination or birefringence. The lab reported that the inclusion of Xuanlei’s MgF₂ optics enhanced signal-to-noise ratio by 40%, enabling more accurate detection of trace gases like methane and ozone. The success prompted a long-term supply agreement, with the client praising Xuanlei’s technical support team for rapid prototyping and detailed material certification documentation. Beyond this project, Xuanlei’s MgF₂ lenses are now widely used in industrial inspection systems, precision metrology tools, and high-power laser delivery systems, where their low dispersion and high durability ensure stable performance even under intense operational stress. This real-world validation underscores Xuanlei’s ability to deliver mission-critical optical components that meet the highest international standards.

• Export Success to Germany, USA, and Japan:

Shanghai Xuanlei Optical Technology Co., Ltd. has established a robust international footprint, with successful exports to key markets including Germany, the United States, and Japan—regions renowned for their stringent quality benchmarks and advanced technological ecosystems. In Germany, Xuanlei’s barium fluoride (BaF₂) lenses were adopted by a leading optical instrumentation firm specializing in ultraviolet lithography systems used in semiconductor manufacturing. The client required lenses with sub-micron dimensional accuracy and surface smoothness to minimize scattering in deep-UV (DUV) laser beams at 193 nm. Xuanlei’s BaF₂ lenses, precisely machined to 42×23×5 mm with a surface flatness of λ/8 and low bulk absorption (<0.1 cm⁻¹ at 193 nm), were instrumental in improving throughput by 22% while reducing defect rates in wafer fabrication. Similarly, in Japan, a major electronics manufacturer selected Xuanlei’s calcium fluoride (CaF₂) lenses for use in high-resolution industrial inspection systems. These lenses provided unmatched transmission uniformity and low dispersion, enabling clearer imaging of microelectronic components during quality assurance testing. The Japanese partner noted a 35% improvement in defect detection sensitivity compared to previous suppliers. In the United States, Xuanlei’s lanthanum fluoride (LaF₃) membranes were integrated into fluoride ion sensors used in environmental monitoring networks. Their high selectivity and long-term stability allowed for reliable detection of fluoride levels in groundwater, even in harsh chemical environments. These case studies reflect Xuanlei’s ability to not only meet but exceed the expectations of global clients. By maintaining ISO 9001 and IATF 16949 certifications, along with rigorous incoming material inspections and full traceability, Xuanlei ensures compliance with international standards. The company’s export success is a testament to its product quality, technical competence, and customer-centric approach—making it a go-to supplier for advanced optical solutions worldwide.

--- Research and Development Initiatives ---

• Collaboration with Academic Institutions:

Shanghai Xuanlei Optical Technology Co., Ltd. exemplifies the power of industry-academia collaboration through its strategic partnership with the Chinese Academy of Sciences (CAS) Shanghai Silicate Research Institute. Since 2021, this joint R&D initiative has focused on developing novel electro-optic materials designed for next-generation optical communication systems, particularly those leveraging high-speed data transmission in fiber-optic networks. One landmark achievement emerged in 2023 with the successful development of a new potassium titanyl phosphate (KTP)-based composite material optimized for frequency doubling in telecom lasers. The material demonstrated a 45% increase in conversion efficiency compared to conventional KTP crystals, while maintaining excellent thermal stability and low optical loss. This breakthrough was validated in a pilot deployment by a Tier-1 telecommunications provider in Shanghai, where the new material enabled faster signal modulation and extended transmission range without signal degradation. The project also led to the filing of three international patents and the publication of peer-reviewed papers in Optics Express and Applied Physics Letters. Beyond material innovation, Xuanlei and CAS jointly established a dedicated R&D lab within the company’s facilities, equipped with advanced characterization tools such as FTIR spectrometers, ellipsometers, and pulsed laser deposition systems. This collaborative ecosystem accelerates the transition from lab-scale prototypes to commercial-grade production. Additionally, the partnership includes student internships and joint training programs, fostering talent development in optical materials science. These efforts underscore Xuanlei’s forward-looking vision: not just to manufacture today’s optical components, but to pioneer tomorrow’s technologies. Through sustained investment in R&D and deep academic ties, Xuanlei remains at the forefront of innovation in the global optical materials industry.
