We build the optical backbone.
5-axis precision CNC, black-anodized internal walls to suppress stray reflection, ID/OD concentricity within 5 μm. Every dimension on a lens barrel drives optical performance — we own the details in-house.
The backbone of optics starts with the barrel.
A lens barrel is the spine of any optical system — it sets lens spacing, alignment and mechanical stress. We machine ours to ±0.01 mm.
Precision Lens Barrel
Aluminum / stainless / brass. Black anodized inner walls to suppress stray reflection. ID/OD concentricity within 5 μm.
Lens Mount & Retainer
Press-fit and threaded retainer rings with thermal-expansion compensation. Optional auto-centering structures.
Optical Assembly
Lens insertion, alignment, bonding and optical-axis measurement in-house. MTF reports provided.
Custom Tubing
Drawing-based barrels for machine vision, inspection and medical imaging — from single prototype to volume.
