Compass™ sets the bar for precision metrology of spherical, aspherical, and freeform micro lenses and their injection molds typically employed in smartphone cameras. ZYGO's metrology systems enable manufacturers to improve quality and yield of their processes, while lowering metrology costs. To accomplish this, Compass utilizes CSI technology and advanced software algorithms, together with an automated multi-axis staging system to deliver surface form and deviation, texture, and relational (dimensional) parameters – all without contacting the precise optical surface. Leading manufacturers have adopted Compass to help optimize their manufacturing cycle. Applications include: • Combined form deviation and relational metrology: one non-contact tool can measure both the complete optical surface and evaluate the deviation from design prescription as well as inspection of mechanical datums and interlocks needed to construct complete camera modules. • Production optimization: Compass supports export of metrology data to optical modeling software and Diamond Turning optimization platforms such as Diffsys™. • Reverse engineering: When the prescription is unknown, measurements are possible using the unique 'follower mode' which tracks the optical surface to generate a full surface map, which can then be analyzed using the asphere form tools. Compass is ideal for precision small optics applications requiring complete characterization of the optical surface and mechanical datums.
