In automation applications, Z focusing refers to the precise control of vertical positioning (along the Z-axis) to maintain accurate focus during processes like imaging, inspection, or metrology. It's critical in fields such as microscopy, semiconductor manufacturing, and digital pathology, where fine adjustments at the nanometer scale are often required. Z focusing systems, such as direct drive or lead screw-based stages, enable automated, repeatable movements, enhancing throughput, accuracy, and consistency in tasks that involve high-resolution imaging or laser processing.
