3D Surface Profiling Of Micro-Lenses: How To Improve Performance

High-performance motion controllers and positioning systems and advanced sensor technology play a key role when it comes to profiling the surfaces of the minute components and features with high accuracy and speed. The selection of sensor technology hinges on parameters like sensor resolution, measurement range, and data acquisition speed.

If a laser-based sensor is employed, the size of the focal spot or measurement field or viewing area, and the capacity to focus are also critical considerations. The motion control system should be set up in a manner that allows the sensor to be positioned swiftly and accurately at the point or within the areas of interest. This might demand rapid movement to the position with minimal settling time, and speedy, uniform scanning of a designated area.
