Our black hard anodized aluminum optical lens barrels are precision CNC machined to meet the demanding requirements of optical instrumentation and imaging systems. The multi-step telescopic design enables precise focal length adjustment while maintaining optical axis alignment. We use high-grade aluminum alloys, typically 6061-T6 or 7075-T6, combined with a durable black hard anodized finish (Type III) that provides excellent wear resistance, corrosion protection, and minimizes internal light reflection. Our multi-axis CNC turning and milling centers achieve tight tolerances, ensuring smooth telescopic motion and accurate component stacking. Each lens barrel is precision machined to sub-micron tolerances to preserve optical performance. We provide full inspection reports and ISO 9001-certified quality assurance.
