NSI Microscopy Inspection Automation have launched their New Electrically Tuned Liquid Lens Modules allowing ultra high speed refocusing allowing you to reduce your cycle times by removing the constant manual refocusing of optical inspection.
Advantages:
Traditionally conventional glass optics are used to automatically zoom into a defect but this can sometimes be too slow to achieve the correct cycle times and that is why liquidly tuned lenses are used to move to preselected positions rapidly finding defects on the way.
