|Orange Peel and DOI measurement on high to semi gloss surfaces|
|… appearance control is no longer limited to final topcoat inspection. Like the wave-scan DOI, the optical profile of high gloss surfaces is detected using a laser light source. An additional, infrared - high energy LED allows measuring the same structure spectrum (0.1 - 30 mm) on medium gloss surfaces. The dullness measurement is recorded with state-of-the-art CCD camera technology. It gives information on the image forming qualities of the surface caused by structures < 0.1mm.|
|Close the appearance control loop for the entire paint process|
|Thus, the surface quality after each paint process step can be objectively evaluated. No more guessing which substrate layer is influencing the final appearance. The wave-scan dual will help you to objectively analyze appearance problems and reduce the time necessary for trouble shooting.|
|Example: Influence of Steel Quality on Final Appearance|
|Step 1: Appearance Control after E-coat||Step 2: Appearance Control after Primer Surfacer|
|Same E-coat system was applied on rough and smooth steel. The influence of rougher steel can be seen in increased Wb and Wc-values.||The primer surfacer was applied on both panels. The roughness of the steel quality can still be detected in increased Wb and Wc- values. This primer system could not completely cover the steel influence.|
|Step 3: Appearance Control after Topcoat|
|The final appearance shows higher shortwave values on the rougher steel panel. Therefore, the smooth panel will appear more brilliant.
wave-scan dual – a diagnostic tool for trouble shooting and optimizing appearance Now, you can establish appearance specifications for each paint layer to ensure the final appearance is always on target
|Objective and reliable appearance data|
|Easy to use with one hand|
The instrument is operated with a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack and transfers the measured data to the PC.
Optionally, the instrument can be operated with 3 standard mignon alkaline or rechargeable batteries - good for 1000 readings.
