Better visibility.
Better coating control.
OptiSense is a German technology company specializing in non-contact, non-destructive coating thickness measurement for industrial applications.
Our PaintChecker technology enables manufacturers to measure uncured powder coatings, wet coatings, and cured coatings without touching the surface.
By bringing thickness measurement closer to the coating application process, PaintChecker helps production and quality teams identify variation earlier, optimize coating parameters, reduce rework and material waste, and improve process consistency.
From flexible manual measurements with PaintChecker Mobile to automated and inline process control with PaintChecker Industrial, our goal is simple:
Give manufacturers reliable coating thickness information where and when it can make the greatest difference.

Dr. Nguyen Thao
Regional Sales Manager (Asia) | OptiSense
I work with manufacturers, paint shops, system integrators and coating technology partners to identify where better coating-thickness visibility can improve process control and production performance.
My goal is not simply to introduce a measuring device. I work with customers to understand their coating process, the areas where thickness is difficult to control, and the cost of discovering variation too late.
Together with our technical team in Germany, I help evaluate applications and determine how PaintChecker can be used — from manual process optimization to automated and inline measurement.
If you are looking to improve coating consistency, reduce rework, or gain better visibility before the coating result becomes permanent, I would be pleased to discuss your application.
