There are several points in automotive parts manufacturing process where coating thickness can be critical and requires quality control: outer hardcoat layers (scratch- resistant), inner anti-fog layers for polycarbonate lenses, hardcoat on base reflector plates, hardcoating on bumper covers and many other components.. Each of these coatings presents a unique set of measurement challenges: low optical contrast between polycarbonate and coating material, inter-penetration (IPL) interface layer, colored parts (e.g. red), reflective texture on the part surface, etc.
MProbe VisHC system provides robust and easy to use solution that allows to measure layers directly on the product. Manual probe MP-FLVis is connected to system with a flexible fiberoptics cable. The probe conforms to the curvature of the sample and accurate measurement can be performed easily. It is used for measurement of the parts larger than 1” (25mm). Small measurement spot (<200 µm) reduces the effect of backside reflectance. MProbe VisHC software uses advanced Thick Film algorithm for HC films and curve fitting algorithm for anti-fog coatings. Algorithms can be easily adjusted/trained to measure even most challenging samples. Measurement process is easy for inexperienced operator to use and understand
