CASE STUDY: Autofocus Module Quiet motion with infinite bearing life. When you need 200 microns of precision motion why use traditional bearings and rails? As feature sizes decrease, camera based imaging systems need auto-focusing mechanisms to produce good data. Because travel distances are typically in the 100 to 1000 micron range for auto-focus applications, traditional linear bearing or guide rail based solutions are bulky and expensive. Our client challenged us to develop a compact, high precision motion stage for their new product line. What We DidSimplexity developed a prototype focusing module that replaced traditional bearing rails with a flexure (aka a compliant mechanism). The flexure consists of parallel plates that act like a four-bar-linkage over a limited motion range. The m
