Hardcoat Thickness Measurements

polycarbonate thickness measurement

Filmetrics systems are used widely in the automotive and aviation industries for thickness measurement of hardcoats and other protective films. The F10-HC is specially designed for the curved surfaces and multiple layers (e.g., primer/hardcoat) encountered in these applications.

Application Note Request

Automotive Headlamp Applications

There are multiple points in automotive headlamp-assembly manufacturing where coating thickness is critical to quality. The thickness of the outer hardcoat layers and inner anti-fog layers on polycarbonate lenses and the base coat on reflectors are all important. Each of these applications offers a unique set of challenges and Filmetrics has developed the software, hardware, and applications knowledge to deliver the right solution.

Filmetrics offers free trial measurements - results are typically available in 1-2 days.

Thickness Measurement Example

Reflectance data was collected using our F10-ARc system with optional HC upgrade which allows thickness measurements. This instrument uses an optical contact probe which inherently reduces the effect of backside reflections.

The surface of the acrylic sheet is placed on the contact probe. The spectral data is collected and then automatically analyzed by FILMeasure to determine the coating thickness. There was a coating of primer and hardcoat with very similar refractive indices on this particular acrylic sheet.
