The LightGuide technology is used in the LUMIMAX® lights of the LG series. The light from High Power LEDs is fed into a structured light guide plate and outcoupled either diffused or collimated over the entire light field.
With this new technology, the lights achieve a homogeneity of up to 90%.
- A diffuse area light is positioned behind the object
- The contours of the test object are lit in order to inspect outlines as well as free inner contours
- Area of application: level control, damage inspection in transparent or semitransparent object surfaces, type and position detection

Image aquistion with diffuse backlight
Variants with additional collimation accessories improve image contrast enormously. Thus, they are often recommended as a cheaper and space-saving alternative to expensive and long-constructed telecentric lighting. In addition, the collimation minimises the glare effect at manual workstations and in the direct machine environment. The LED Area lights can be used with and without a camera hole as incident and backlight.
