Precision CNC Turned AL6061 Aluminum Lens Retaining Ring With Custom Red Anodizing

This precision CNC turned lens retaining ring is engineered for professional optical instruments, camera systems, and photonic device assemblies where secure lens retention, precise axial positioning, and ergonomic manual adjustment are essential.

Manufactured from Aluminum Alloy 6061, this component delivers an ideal balance of lightweight performance, excellent machinability, and good corrosion resistance — making it a preferred choice for optical barrel components and lens mount hardware.

• Dual-band diamond knurling on outer surface for consistent, slip-free grip during manual adjustment
• Precision-turned smooth inner bore with tight cylindrical tolerances for concentric lens seating
• Lateral set-screw port for positive locking to prevent unintended rotation
• Optimized for gloved-hand operation and field-use conditions

Features custom red anodizing applied through a controlled Type II sulfuric acid anodizing process. This creates a hard, dense aluminum oxide layer that significantly enhances surface hardness, corrosion resistance, and abrasion durability while delivering a visually distinctive, brand-consistent appearance. Custom colors across the full spectrum are available to match your product identity.
