Precitec Optronik: Non-contact coating thickness testing with laser
Precitec Optronik is presenting a non-contact laser coating thickness measurement system at SurfaceTechnology Germany 2026. The photothermal technology works non-destructively and delivers precise results even with complex geometries and different materials.
Modern coating applications require precise control of coating thickness to ensure function and durability. Conventional, contact-based measurement methods are often limited in their ability to deliver satisfactory results due to material combinations, roughness or complex geometries. The patented laser-photothermal technology from Precitec Optronik GmbH now offers a non-contact, non-destructive alternative.
Coating thickness measurements with laser technology
The coating surface is heated locally by a laser. The resulting heat wave spreads through the coating and is partially reflected at the interface to another material or defect. Precitec's Enovasense products implement this laser-photothermal principle in compact, vibration-resistant sensors for industrial use. The technology enables reliable coating thickness measurements on a wide variety of materials - regardless of shape or surface structure. Precitec Optronik also offers optical sensors for quality inspection that are based on chromatic confocal and interferometric technology and measure distances, thicknesses and surface textures precisely and quickly without contact or destruction. Precitec Optronik will be exhibiting at SurfaceTechnology Germany 2026 in Hall 1, Stand C18.
