MFU Series

These Coaxial Lights provide collimated lighting from behind the workpiece. This suppresses the wraparound of light and enables precise dimension measuring and appearance inspection.


We achieved collimated lighting through unique lighting technology.
It allows for highly-accurate imaging that prevents light from wrapping around the workpiece. It allows for convergence to match the imaging-side lens in use.

Imaging Example

Exterior imaging of a screw

Exterior imaging of a push pin

When the user looks at a clear resin push pin with diffused light from a Flat Light illuminated from the rear, the clear part appears clear. However, with collimated light, the light is refracted by the clear resin, and the whole pin appears black.

Imaging of the exterior and dimensions of a condenser

If you view it with diffused light of Flat Light illuminated from the rear, the light wraps around the side of the condenser body. However, with collimated light, that wrap around is prevented and the thickness of the wires is also imaged evenly.
