Looking for the optimal solution for your application?


We develop and produce laser sensors and optoelectronic sensors in the IR, visible, and UV range. We provide complete measuring technology solutions.

Most of our sensors come with an easy-to-use PC software that considerably facilitates evaluation. The sensors are used for the inspection and measurement of physical values such as distance, thickness, position, color, gloss, as well as spray density, contrast, fluorescence, and polarisation.
