Demanding laser processes will benefit from a control mechanism that enables improved throughput and accuracy.SUSANNE ABL AND JOHN FLEMMER, SCANLAB GMBH, AND JASON GOERGES, ACS MOTION CONTROL INC.High-precision, high-throughput laser micromachining typically requires galvo scan heads with a short focal length, which in turn produces a small image field, or field of view (FOV). However, a growing number of high-tech manufacturing areas, such as OLED display fabrication, require the processing of workpieces larger than can fit into these reduced image fields, while simultaneously requiring a high level of accuracy and throughput. The same applies for many other laser micromachining applications, such as two-photon polymerization or the processing of glass, foils, and films.

Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookMicroassembly: Minimizing Error and Maximizing Precision: Optimizing positioning systems for microassembly processes requires an understanding of the potential errors that can cause precision part placement to go awry.Progressive assembly operations such as guiding, gluing and bonding often take place around a static package in three-dimensional space.
