How do I know which light I need?
Light selection is dependent upon the part size, surface features, part geometry and system needs. Generally speaking, you can use the following chart to select a lighting technique. For help, contact one of our distributors or a NERLITE sales engineer.
| Applications/Desired Results |
Lighting Technique |
|
Locate or measure outside dimensions - View openings (e.g., drilled holes) - Diminish clear glass or plastic housings - Measure thickness of materials
|
Backlight |
Illuminate flat, diffused surfaces - Control costs - Good for diffused surfaces
|
|
Fill-in center of image with light - Evenly illuminate flat shiny surfaces - Enhance scribed, indented or embossed features (when on-axis lighting is required) - Create contrast between specular, diffuse or absorptive surfaces
|
DOAL or
COAL |
Even out very bumpy specular surfaces - Diminish Clear Overcoats or Coverings - Reduce Shadows - Differentiate specular, diffuse or absorptive features on a bumpy surface
|
CDI |
Even out slightly bumpy specular surfaces - Reduce shadows - Differentiate specular, diffuse or absorptive features on a slightly bumpy surface - Achieve near-CDI effect at reduced cost
|
SCDI |
Illuminate only the contour of a part - Enhance embossed or engraved surface features - Differentiate between specular & diffused surfaces
