Machine Vision Products - STEMMER IMAGING



With Europe’s largest selection of leading machine vision technology


In 2008 Optotune invented a new principle for focus-tunable lenses based on elastic polymer membranes, which allows for focusing electrically within milliseconds free of mechanics. Since then the technology has matured and today Optotune provides cutting-edge focusing solutions for several industries including machine vision, lighting, laser processing and ophthalmology – all manufactured in Switzerland.

While Optotune's R&D team, which has grown to over 30 engineers, continues to innovate and further develop a variety of adaptive optical components, the use of focus tunable lenses in machine vision and microscopy has become one of the company's main applications.

Recent development improved the focus reproducibility by using temperature compensation schemes or even integrated optical feedback, so that customers can also control the lenses in an open loop environment. Furthermore, Optotune provides a driver for all lenses including open communication protocols to facilitate system integration.
