LED Dark Field Illumination by LUMIMAX®

LED Dark Field Illumination by LUMIMAX for Machine Vision Applications

With their radial and flat incoming light, LUMIMAX® LED dark field lights are the preferred option for inspecting surfaces. Their special light guide means that this illumination geometry can be used to show edges, cavities and other surface defects in high contrast.
The lights in the DFL series are available in several sizes for continuous and flash mode.
Integrated controllers, powerful LEDs and standardised LUMIMAX® connections guarantee simple and stable integration into the system environment.
