CO2 Technology Continues to Evolve
The first commercial application for CO2 lasers was wire stripping — using a large, flowing gas system that required regular repair and maintenance. Today, the latest developments for this type of laser include a system scheduled for launch into space; it is small, lightweight and capable of five years of continuous operation. Things have changed. When selecting laser technology for almost any application, systems integrators and end users both look for low cost and high reliability. Along...

Positioning Precision Takes Center Stage
These basic laws of physics can frustrate any system designer’s best efforts to move a component from point A to point B rapidly and to stop it on the desired target. In most cases, the positioning system must repeat this action over and over with...

Positioning Systems Make Submicron-Level Moves
Demanding by their very nature, submicron and nanometer-scale positioning tasks are further complicated when the management of motion is under vacuum or when it requires extended travel, more repeatability, higher speed or greater uptime — of...
