Ideal for Optics Products: Camera Lenses, Medical Optical Lenses, Automotive Headlight Lenses, Industrial Detection Lenses | ±0.001mm Core Precision | Compatible with Optical-Grade Resins (PMMA, PC, Optical Glass-Filled Resin) | Supports High-Transmittance Surface Requirements (Light Transmittance ≥92%)

This high-precision electroformed optical lens core is specially developed for the optics industry, focusing on solving the core pain points of "poor light transmittance, low molding precision, and unstable optical performance" in traditional optical lens manufacturing. Unlike conventional machined cores that easily cause surface scratches or stress-induced birefringence, our electroformed core adopts layer-by-layer nickel ion deposition technology to form a dense, stress-free structure with ultra-smooth surface (Ra ≤0.005μm).

The core’s high-precision contour replication (±0.001mm tolerance) ensures that the molded optical lens maintains perfect curvature and flatness, while the optical-grade polishing process minimizes surface defects, enabling light transmittance of the final lens to reach ≥92%. We provide direct service from technical communication to custom processing, eliminating intermediate links to accurately match the personalized needs of different optical products (such as aspherical lenses for cameras and high-transmittance lenses for medical endoscopes). Compliant with ISO 13485 (for medical optics) and IATF 16949 (for automotive optics), it is a reliable core component for optics manufacturers pursuing high-quality lens production.

With advanced electroforming technology and laser interference detection, the core’s key dimensions (diameter, curvature radius) are controlled within ±0.001mm, and surface flatness is ≤0.0005mm. This avoids light refraction deviation caused by core contour errors, ensuring that the molded lens meets strict optical index requirements (such as resolution, focal length accuracy). For aspherical and free-form surface lenses that are difficult to process, the electroforming process can accurately replicate complex curved surfaces with 99.9% fidelity.

The core surface is polished to Ra ≤0.005μm, which is far lower than the surface roughness of traditional steel cores (Ra ≥0.01μm). The ultra-smooth surface reduces light scattering and reflection during lens molding, making the light transmittance of the final optical lens reach ≥92%. It is especially suitable for high-end optical products that require high light transmittance, such as medical imaging lenses and automotive ADAS camera lenses.

• Stress-Free Structure: Electroformed core has no internal stress, avoiding deformation under high-temperature optical resin molding (180-250℃) and ensuring consistent lens quality across batches;
• Wear Resistance: Nickel-cobalt alloy material (50-55 HRC) resists abrasion from repeated resin injection and demolding, supporting 500,000+ production cycles without surface damage;
• Low Contamination: High-purity nickel material has no harmful substance precipitation, meeting the cleanliness requirements of medical and food-grade optical products.

We provide direct one-stop service for optics manufacturers: direct technical communication with professional optical engineers to clarify core requirements; custom processing based on 3D optical design files (STEP, IGES); pre-production sample verification (providing optical performance test reports of molded lenses); post-sales maintenance guidance (core cleaning, polishing maintenance) to ensure efficient production and stable quality.
