Résumé : |
The author reports on how to master the challenge of bringing true daylight into the laboratory.
Uniform colour is directly associated with high quality and influences our purchasing decision. This is especially true for multi-component products consisting of different materials and/or being produced by different suppliers. The human eye is often the final judge for approving a new design. Therefore, the visual inspection conditions need to be standardised to guarantee repeatable visual results.
The most important colour match is under naturel daylight. The CIE defined several standard D illuminants with D65 being the most important one. The lames used in a light booth must simulate D65 as close as possible. Until now, fluorescent tubes were used to simulate D65. A new unique lighting setup is now able to achieve class A quality by simulating CIE D65 with a smart combination of filtered halogen lamps and LEDs. |
