What we check


Test solutions for semi-transparent plastics

With the help of OCT sensors, we are able to check wall thicknesses and barrier layers on foils and structured surfaces such as Fresnel lenses and lab-on-a-chips. Our sensors can be used offline as well as inline, for example in the production of endless products such as hoses.

An important field of application is the non-destructive measurement of the thickness of layer systems, for example made of ethylene-vinyl alcohol copolymer (EVOH), in food packaging. The measuring system checks the total layer thickness as well as the thickness of the barrier layer.

The high measuring frequency of up to 200 kHz makes it possible to use it in production machines for 100 percent inline control. MABRI.VISION supplies different systems from punctiform 1D measurements to 3D systems that scan a large measuring field with a measuring rate of up to 200 Hz.
