Auto Focus

Increase Machine Throughput With Advanced Dynamic Focus Control

ACS motion controllers enhance precision automation systems with dynamic autofocus tracking by improving servo bandwidth while minimizing tracking error for optimal focus results. Our Autofocus sophisticated real-time control algorithms are designed to transition seamlessly from position to focus control and offer advanced functions to address more demanding applications with non-collocated sensors or diffuse reflection zones. These features can be used for various automated inspection and vision-based applications, including semiconductors, metrology inspection systems, micro-electro-mechanical systems (MEMS), flat panel displays, biomedical and laser processing.
