Precision processing of optical equipment lenses
Our CNC machined optical lens barrels are precision engineered for the exacting requirements of camera lenses, microscope objectives, and telescope eyepieces where bore accuracy, surface finish, and mechanical smoothness directly impact optical performance. Each lens barrel is manufactured on advanced 5-axis CNC machining centers, maintaining tolerances as tight as +/-0.01mm to ensure precise lens alignment and smooth focusing operation.
We specialize in custom lens barrels featuring helical focusing tracks for smooth manual or motorized focus adjustment, precision bore diameters for lens element retention, mounting flanges for camera body attachment, and integrated aperture mechanisms. Our multi-axis CNC capabilities enable complex internal and external geometries including undercuts, grooves, and precision threads - all machined in single setups for maximum concentricity and accuracy.
Components are manufactured from aerospace-grade aluminum alloys 6061-T6 and 7075-T6, selected for their excellent stability, low thermal expansion, and machinability essential for optical applications. The material provides sufficient rigidity to maintain optical alignment while keeping lens weight manageable. Mirror-polished surface finish reduces friction in focusing mechanisms and enhances the professional appearance of finished optical products.
Our ISO 9001:2015 certified quality management system ensures consistent quality across every production run. Each lens barrel undergoes comprehensive dimensional inspection using coordinate measuring machines (CMM) to verify bore diameters, thread accuracy, and concentricity. Surface finish is verified with profilometers to ensure mirror-quality specifications. Complete inspection reports and material certificates are provided with every shipment.
These precision lens barrels serve applications across professional camera lenses and photographic equipment, microscope objectives and imaging systems, telescope eyepieces and optical accessories, industrial machine vision cameras, medical endoscopes and imaging devices, and scientific research instruments. They function as the critical structural housing that maintains precise lens spacing and enables smooth mechanical adjustment of optical focus.
We support your complete lens development cycle with flexible manufacturing options. Validate designs with rapid prototypes, refine through small batch testing, and scale to high-volume production for commercial lens manufacturing. Our experienced engineering team provides DFM feedback to optimize designs for manufacturability, cost, and optical performance.

Q: What bore tolerances can you achieve for lens mounting?
A: We achieve H7 or better tolerance on lens mounting bores with controlled roundness and cylindricity within 0.005mm. This precision ensures proper lens fit, maintains optical axis alignment, and prevents stress on delicate optical elements.
Q: Can you machine helical focusing tracks?
A: Yes, our 5-axis CNC capabilities enable precision helical tracks for focusing mechanisms. We can machine various thread pitches with lead accuracy within 0.01mm to ensure smooth and precise focus adjustment throughout the travel range.
Q: What surface finish can you achieve for lens barrels?
A: We achieve mirror-polished surface finish with Ra 0.2-0.4um through precision machining. This level of finish minimizes friction in focusing mechanisms, reduces wear, and provides the professional appearance required for high-end optical products.
Q: What materials do you recommend for lens barrels?
A: For most lens applications, we recommend 6061-T6 aluminum for its excellent stability, machinability, and cost-effectiveness. For professional lenses requiring maximum rigidity, 7075-T6 provides superior strength. Both alloys offer low thermal expansion essential for maintaining focus stability.
Q: Do you provide black anodizing for light control?
A: Yes, we coordinate black anodizing through certified partners. Black anodizing is commonly used for lens barrels to minimize internal reflections, control stray light, and provide professional appearance. Hard anodizing is also available for enhanced durability.
Q: What is your typical lead time for lens barrels?
A: Prototype samples: 5-10 days depending on complexity. Small batch (10-100 pcs): 2-3 weeks. Medium batch (100-1000 pcs): 3-5 weeks. Large production (1000+ pcs): 5-8 weeks. Fast delivery and consistent quality have earned high customer satisfaction.
