What our customers say

Managing Director Dr. Felix Zabka relies on OptiSense for quality testing at GSB member ConceptColor. The real-time coating thickness measurement technology from OptiSense is used directly in the line.

Good investments instead of good intentions

The trend barometer just published by the trade journal Besser Lackieren shows the highlight topics in 2021. Following employee growth, investments in measuring devices are in second place. The coating companies are investing heavily in order to keep their finger on the pulse of times and to stay competitive.

For 2022, the following applies: Instead of good intentions, it is better to invest well - for example in a new PaintChecker coating thickness measuring system from OptiSense. Arrange a demonstration:


For the beginning of the new year

"And there is magic in every beginning," wrote Hermann Hesse. That's what we wish you for the beginning of the new year.  May the glow last for the entire twelve months - combined with good luck and, of course, plenty of health!

Presentation: Measuring coating thickness in pipes, on edges and curves

In the digital measuring and testing technology forum of the magazine Besser Lackieren, Jörg Mülleneisen, Sales Manager OptiSense, presented solutions for "tricky" coating thickness measurements in pipes, on edges and curves to experts of the industrial painting industry. Take a look at our presentation:

Real-time coating thickness measurement directly in the line at ConceptColor

Coating thickness measurement is a key technology for quality assurance in the coating industry. To achieve this, however, the testing technology must be increasingly interlocked with actual production. This is the path ConceptColor has taken - extremely successfully, as the interview with Managing Director Dr. Felix Zabka and Deputy Production Manager Silke Goldmann- Rohde shows.

OptiSense's Q-DAS certification ensures process quality

Coating companies want to gain detailed insights into their data and also analyze their history in order to improve processes. A conversation with managing director Dr. Jens Heymans shows the added value of the production data processed and analyzed by OptiSense.

OptiSense offers a new recalibration service in accordance with VDA 5

Measurement processes are subject to a variety of influencing factors that lead to measurement uncertainties. In its volume, the VDA names 5 typical influencing variables to be examined, but requires the user to ensure that no relevant variables are neglected. OptiSense supports the coaters in this process: With the “recalibration”, the sensor manufacturer from Haltern ensures that its coating thickness measuring devices comply with the demanding VDA 5.

European Coating Show shows future coating trends

At the European Coating Show as the annual lighthouse event, top-class speakers from industry and science take a look at the coating industry of tomorrow. At the interesting mixture of well-known and top-class speakers, OptiSense managing director Georg Nelke was also present with the lecture Design of optical sensors for quality IIOT projects in coating applications.

The OptiSense sales team continues to grow

OptiSense, market leader in contactless coating thickness measurement, is further expanding its proximity to customers and enlarging its sales team: on board are Sascha Schmidt, who has recently become responsible for hand-held measuring devices, and Patrick Voos, who now strengthens the field sales force for industrial measurement solutions.
