AL7075 Aluminum With Powder Coating Finish Precision CNC Machined Lens Barrel Rings

These precision CNC machined lens barrel ring components are purpose-engineered for professional optical instruments, telescope assemblies, and high-performance imaging systems where structural strength, lightweight construction, and superior surface durability are simultaneously required.

Manufactured from Aluminum Alloy 7075, one of the highest-strength aluminum alloys available, delivering:

• Exceptional tensile strength
• Outstanding fatigue resistance
• Excellent dimensional stability

This premium material choice is ideal for optical housings subjected to mechanical stress, thermal cycling, and field-use conditions.

• Precision-milled longitudinal fluting grooves for enhanced manual grip and weight reduction
• Smooth precision-bored inner diameter for accurate, concentric lens or tube seating
• Lateral threaded set-screw ports for secure locking at any rotational position
• Critical for maintaining precise optical alignment during operation

The matte black powder coating finish is applied through an electrostatic spray and thermal cure process, forming a tough, impact-resistant polymer layer that delivers:

• Outstanding scratch resistance
• Superior corrosion protection
• Complete internal light-reflection suppression
• Essential for stray light elimination in precision optical barrel assemblies

• CMM dimensional inspection
• Coating adhesion and thickness testing
• Bore concentricity verification
• Surface finish analysis

Custom dimensions, groove patterns, and coating colors are available upon request.
