Applications Addressed: Automotive - inspection Marine - accent Outdoor/Signage – Security, spotlight, Low level illumination Rail – reading and warning lights Architectural – projection, accent Military - inspection Decorative - backlighting Pharmaceutical – high speed inspection, color rendering, OCR

7. Lighting – Why so important? 80 % of success depends on Proper illumination Contrast Resolution Repeatability Speed of processing Cost of system Garbage in – Garbage out Lighting is an Art form – Distances – angles - Brightness No Substitute for Hands-on

8. 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

9. 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 Transmitted ( Back) Illumination Diffuse Dome Illumination

10. Light Source Types Solid State LED – Electro-luminescent output Halogen – Gas filled – filament Fiber Optics is the conduit Xenon – Gas filled – arc Fluorescent – Gaseous discharge

11. The LED advantage Long lasting – 100k+ hrs Pricing- Cost of Ownership From Monochromatic to Infinite Color tuning. Design flexibility Voltage flexible Shock/vibration resistant “ Cold” light Instant On - NANOsec’s Intensity Adjustable Intensity unlimited High efficiency

12. Some LED background Die structure – PN junction 3mm and 5mm Surface mount “ Cold light” Heat

13. Some LED background LED Parameters Current driven “ White” LEDs

14. Front Lighting - Directed Creates contrast and shadows through incidence angles Good control of contrasts May create unwanted shadows Design Flexible in setting up multiple sources Uneven Intensity – Inverse Sq Law Good for long arrays

15. Front Lighting - Diffused Creates contrast and shadows through incidence angles Softer – non directional lower contrast Reduced glare on specular objects Design Flexible in setting up multiple sources Easy to implement Uneven Intensity – Inverse Sq Law E=1/d ²

16. Near Axis – (Brightfield) Ringlight Generally good for standard applications. Provides a uniform intense shadow free illumination. Not suitable for reflective surfaces Camera Mountable Sizes from 75mm to 150mm Easy alignment

17. Off-Axis (Darkfield) Ringlight Highlights defects on highly specular surfaces Surface Defects Stratches Minor relief Occlusions Solder pads

18. Coaxial Illumination Light on axis with camera line of sight Eliminates shadows Excellent for highly specular surfaces Uniform across field of view

19. Dome Lighting Non-directional diffuse light eliminates glare and shadows For use on highly reflective surfaces Eliminates the Inverse Square law E=1/d ²

20. Back Lighting Sharp silhouettes of objects for edge detection and even illumination for opaque and transparent targets Diffuse – Collimated - Polarized Provides dimensional analysis Ideal for Transparent Packaging/product verification Drill holes and perforations – sharp edges Birefringence

21. Metaphase Technologies Value-Added Lighting solutions Line Lighting Sharp silhouettes of objects for edge detection and even illumination for opaque and transparent targets Works with Line scan camera Higher resolution Higher Intensity Topography

22. Custom Structured Lighting Combinations of basic setups Bk + Diffuse Dome light Better resolution Higher Intensity Multiple Topographies Multiple artifacts

23. Enhancements and beyond the Human Eye Filters Complimentary colors increase contrast Neutral Density (ND) filters provide flat attenuation Reduces Ambient noise Polarizing Reduces specular glare IR Contrast features; dyes - 840-940nm Invisible to naked eye – silicon sensitive Benefits – Eliminates light noise; Saves on shielding UV Fluorescent dyes
