Core Advantages of Customization Capabilities

High-Precision Manufacturing Processes: Utilizing CNC precision grinding, polishing, and sub-nanometer surface treatment technologies, combined with high-precision optical centering and coating processes, we control the curvature radius error of spherical lenses within ±0.005mm, achieve a surface form accuracy of λ/20 (λ = working wavelength), and maintain a surface roughness of Ra < 0.3nm. Our self-developed specialized processing and testing equipment ensures that lens optical performance reaches industry-leading levels, meeting the stringent precision demands of the optical communication and laser industries.

Fully Flexible Parameter Customization: Backed by a professional optical design team and simulation software like Zemax and Code V, we precisely customize spherical lens parameters—including materials, curvature radius, aperture, center thickness, and refractive index—according to the characteristics of the optical communication and laser industries. From single lenses to complex lens systems, optimized designs enable efficient optical energy coupling, beam collimation, and focusing, satisfying diverse personalized optical performance requirements.

Rigorous Quality Control System: We have established a comprehensive, end-to-end quality control system covering raw material screening, production process monitoring, and finished product inspection. Using high-precision equipment such as Fizeau interferometers and spectrometers, we conduct 100% inspections of key lens indicators, including curvature, decentration, transmittance, and surface quality. This ensures stable and reliable product performance, compliant with Telcordia standards in optical communication and ISO 10110 quality requirements in the laser industry.

Applications in Optical Communication and Laser Industries

(A) Optical Communication Field

Fiber Optic Coupling and Signal Transmission: Customized spherical lenses optimize curvature and numerical aperture to efficiently couple laser beams into single-mode or multi-mode fibers, achieving a coupling efficiency of over 98% and significantly reducing signal transmission loss. In optical transceivers and amplifiers, precise spot control minimizes modal dispersion, ensuring stable long-distance, high-speed optical signal transmission.
Optical Network Equipment: Spherical lenses used in optical switches and wavelength division multiplexing (WDM) systems feature customized coating designs, achieving high transmittance and low reflectance for specific wavelengths (e.g., 1310nm, 1550nm). This reduces signal crosstalk, enhances network transmission capacity, and reliability. The high-precision machining of lenses ensures accurate optical path alignment, optimizing signal transmission efficiency.

(B) Laser Industry

Laser Cutting and Welding: For industrial lasers of various wavelengths, such as CO₂ lasers (10.6μm) and fiber lasers (1.06μm), we customize spherical lenses with high laser damage thresholds to enable efficient beam collimation and focusing. By optimizing lens parameters, the spot diameter can be compressed to below 15μm, significantly increasing laser energy density, cutting speed, and welding quality, meeting the high-precision requirements of metal processing, automotive manufacturing, and other industries.
Laser Marking and Surface Treatment: In ultraviolet laser (355nm) marking applications, customized spherical lenses correct chromatic and spherical aberrations through special material selection and aspheric design optimizations, achieving fine spots of < 8μm for clear and durable marking patterns. The lens’s high surface quality minimizes laser scattering, reducing the heat-affected zone on materials and enhancing surface treatment results.
Laser Medical Equipment: In medical devices for laser myopia correction and tumor resection, customized spherical lenses leverage high resolution and low distortion to focus laser beams accurately to the micrometer scale. This reduces damage to surrounding healthy tissues while improving treatment effectiveness. For different medical scenarios, lenses can be customized to fit specific wavelengths and power levels, ensuring safe and efficient device operation.

(A) Optical Parameter Matching

Select suitable optical glass materials (e.g., H-ZF series, zinc selenide) or crystal materials based on the specific wavelength ranges of optical communication (1260 – 1625nm) or lasers (ultraviolet to far-infrared). Integrate system parameters such as beam diameter and divergence angle to optimize the focal length and refractive index of spherical lenses, ensuring ideal collimation and focusing while balancing aberration correction and manufacturing costs.

(B) Environmental and Mechanical Adaptation

For high-temperature, high-power laser environments, we provide lens materials and coating solutions with high-temperature resistance (> 300℃) and high laser damage thresholds (> 10J/cm²). To meet the miniaturization needs of optical communication devices, we customize ultra-thin, lightweight lens structures for compact integration with optical modules. Strict control of mechanical parameters like decentration and surface form accuracy ensures long-term stable operation of the equipment.
