Collimated lighting
Alternatives
Used for applications where standard techniques fail. Tends to be used for very high precision complex applications involving very complicated geometry or when very specific attributes need to be emphasised.
Collimated illumination provides higher precision and edge definition than other lighting. The general principle involves a point source light positioned at the focal point of a lens to produce parallel rays of light. It is possible to get similar results to collimation using light control film but this only provides pseudo collimation in one direction rather than two and is therefore not truly collimated.
Example applications include defining very accurate edges for precision measurements, detection of dents or imperfections in reflective surfaces, emphasising contrast in embossed plastics. Often used in combination with Telecentric (collimated) lenses
Specific models include small backlights, spotlights and Collimated On-Axis Lights (COAL).
