      • Garbage in – Garbage out
      • Lighting is an Art form – Distances – angles - Brightness
      • No Substitute for Hands-on
    • Considerations for Illumination
    • Color or Monochrome
    • Camera; Desired features; lighting; cost;
    • Size of area to be illuminated (FOV)
    • cost; space constraints; lensing; process speed
    • Nature of object – size ; surface ; artifact/s
    • Specular; diffuse; structure of light source; type and size of defect
    • Environmental and mechanical constraints
    • light source; structure; background; wash down? Maintenance
    • Speed of application
    • light source type; stability; repeatability; resolution of detail
    • Service life of light
    • light source type; cost of ownership
    • 6 General Lighting Techniques –
    • Which Best Creates a detectable and repeatable contrast with the desired artifact/s on the inspected object. An object is an optical filter – Light rays are modified in 3 ways – Transmitted ; absorbed; reflected
        • Directional Front Illumination
        • Front Ringlight near axis (Brightfield) Illumination
        • Front Ring off axis (Darkfield) Illumination
        • Coaxial Illumination
