All good things ...

come in threes. Our OptiSense portfolio proves that the best things usually come in threes. Whether industrial test systems, mobile measurement devices or services, our solutions are guaranteed to get to grips with any measurement task, no matter how demanding.

Simultaneous tests on neuralgic parts of an enclosure

The PaintChecker Industrial photothermal measuring device for non-contact, non-destructive coating thickness measurement can operate with multiple sensors at the same time. The sensors are small enough to fit side by side even in confined installation spaces. The tiny, point-shaped measuring spot allows to precisely measure even the smallest components. The device is suitable for wet and dry organic coatings such as paints, varnishes and powders on metal, rubber and ceramics.

OptiSense lecture during SurfaceTechnology 21.-23. June 2022

The top-class SurfaceTechnology forum is the central point of contact for knowledge transfer and exchange of experiences. On Thursday, June 23rd at 2:40 p.m., OptiSense will give a lecture on Mini sensors for layer thickness measurement in industrial environments.

At the international trade fair, around 300 exhibitors present the topic of "surface" in its entire range and including all machining processes. The measuring, testing and analysis technology is also shown on practically all materials - such as metal, plastic, wood, glass or ceramics.

OptiSense develops a new coating thickness inspection system for the battery cells of BMW Group

For a battery to be competitive, it must be inexpensive to manufacture and above all it must be safe. Together with Sturm Maschinen- & Anlagenbau GmbH in Salching and another integrator, OptiSense developed a system for testing the insulating coating of the battery cells, thus making an important contribution to the safety of the new batteries.

Our tube sensor celebrates (into) the first of May

Maypole is the name given to a decorated tree or tree trunk that is erected on the eve of May 1 according to ancient custom. With a maypole of a special kind we bring this old Germanic tradition into modern times: Our Industrial Tube sensor acts as a maypole trunk for the decorated wreaths on this first weekend of May.

Surrounded by flapping ribbons, the Dance into May is apparently a pleasant break from the daily routine of industrial testing for our Tube.

Walpurgis night in Haltern

While the descendants of Walburga in the Harz Mountains are still on the move on traditional brooms on April 30, the witches of Haltern are swinging through the air again this year with powerful propulsion to chase away winter and evil spirits - as the picture tells us.

It shows with a little wink of the eye that the OptiSense sensors are not only used for precise coating thicknesses measurement, but in exceptional cases sometimes serve as flying vehicles for supernatural beings.

In the spirit of Goethe we greet with "Heißa, Walpurgisnacht" all big and small witches, devils as well as ravens - and wish you a relaxing and sunny first of May!
