EVT presents the 'EyeCheck Smart Cameras' with the liquid lens from Optotune. With autofocus optics based on liquid lenses, quality control, sorting, code reading or measuring, for example, can be realized faster than with manually adjustable lenses; the liquid lens refocuses in milliseconds and thus enables switching in the production line without having to change anything mechanically on the optics. The EyeVision 3 software offers an extra command for this lens in the graphical user interface. However, users can also use the new plug-in to compile commands themselves and insert an icon for them in the 'EyeVision GUI'.
