Incident illumination

What is incident lighting?

Incident lighting: The light source shines onto the object from the same side as the camera. Also known as front lighting or direct lighting. Generally incident lighting is used to highlight features on the object which are parallel to the lighting or camera.

Examples of incident lighting include

  • ring-lights
  • area lights
  • line-lights
  • shadow free or "cloudy day"

Vicolux incident illumination products:

 

Ring lights

Application
  • universal light source for top light
  • homogenous lighting of the object plane
  • high luminance, i.e. suitable for high speed processes

    Features
  • LED and HF fluorescent light sources
  • Choice of lenses to focus or diffuse the light
  • radiant inner diameters from 11 mm to 78 mm
  • radiant outer diameters from 40 mm to 112 mm

  •  
    Lighting with through camera view

    Application
  • homogenous lighting of large, not strongly reflecting areas
  • for robotics, for constant lighting of different objects
  • homogenous lighting of slightly curved parts

    Features
  • LED light sources
  • free diameter 50 mm
  • mounting surrounding the camera lens
  • ready to install with controller, tough design
  • different sizes and light colours
  •  
    Directed lighting

    Application
  • emphasize edges and scratches
  • homogenous lighting for diffuse reflecting surfaces
  • completeness checking, presence inspection, reading codes and signs, surface inspection, ...

    Features
  • extremely flat design (down to 11mm thickness)
  • LED light sources
  • radiant field sizes from 29×37 mm up 182×250 mm, custom sizes also available
  •  
    Polarized area lighting

    Application
  • suppression of reflections, with priority for non-conducting materials
  • makes low contrast details visible
  • completeness checking, reading codes and signs at low contrast, control of shiny surfaces, ...

    Features
  • LED light sources
  • linear polarized light
  • radiant area size 46x46 mm
  •    
    shadow free lighting

    Application
  • homogenous lighting of 'problem' parts (very structured parts, surfaces, textures)
  • check for cracks in safety relevant parts (automotive), reading codes and signs on creased foils, ...

    Features
  • LED light sources
  • Most homogenous lighting possible ('cloudy day illumination')
  • free inner space of 127 mm diameter
  • no fan

  • Shadow Free
       
    Modular directed lighting

    Application
  • emphasize edges and scratches
  • homogenous lighting for diffuse reflecting surfaces
  • completeness checking, presence inspection, reading codes and signs, surface inspection, ...

    Features
  • LEDs in 30 x 30mm modules(e.g. 30x300 mm or 240x240 mm)
  • with/without camera-hole (60 x 60 mm)
  • with/without heat sink
  • for OEM customers the lighting is also available without housing
  •
