There used to be a time when appearance control on a product was limited to only the inspection of the final topcoat. But with the introduction of a new member of the wave-scan family, this is no longer the case. The wave-scan dual uses a laser light source to detect the optical profile of a high gloss surface. Additionally, when dealing with a medium gloss surface, a wave-scan dual uses a infrared high energy LED to measure the spectrum.
With the wave-scan dual evulation can take place at each substrate layer to determine which layer is influencing the final appearance. Troubleshooting time is reduced and is kept to a minimum.
It is safe to say that wave-scan technology has changed the way that industries, such as automotive, look at the overall painting process.
