OPTICS DIVISION

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.

OPTICS DIVISION

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.
