LED line lights

The VLX high intensity LED Line Lights are the best solution for Web inspection and Surface inspection applications.

Need more light?

With the development of ever more powerful line scan cameras allowing higher and higher line rates, the limiting factor in many applications is often been the intensity of the available line light being used. Inadequate lighting intensity can compromise the abilities of the line scan camera leading to limited line rates and/or image resolution. With the VLX2+/VLX2 products' liquid cooled LED technology, this limitation can be removed allowing even the highest performance line scan cameras to be reliably pushed their limits for 24/7 high speed image acquisition.

Even where more light isn't an absolute essential, Machine Vision system designers will always tell you that you can't have enough! More light can allow larger depth of focus, lower camera gain settings, headroom to compensate for light decay with time – all will contribute to better images, more tolerant acquisition and easier analysis.

Features and Benefits

Whether your application requires conventional top lighting or backlighting, the flexible format of the VLX LED light range offers a light that will meet your needs - providing up to 2.3million Lux in some cases.
