Solid-State Lasers

The latest AVIA NX series lasers from Coherent, Inc. (Santa Clara, CA) are qswitched, diode-pumped, solid-state lasers that offer output powers as high as 40W at 355 nm. These new lasers implement Coherent's patented pumping technology of the Nd:YVO4 gain medium, which delivers increased overall system efficiency (conversion of input electrical energy into usable light). They also incorporate Coherent’s latest optical mounting technology, called PermAlign 2, which is a simpler and more compact method that yields enhanced stability and greater long term reliability. Reliability is further enhanced through implementation of Highly Accelerated Life Testing and Stress Screening (HALT/HASS) protocols during AVIA NX production.

High-Accuracy Galvo Scanner

The highly repeatable and thermally stable feedback sensors used on the AGV-HPO scanner systems from Aerotech (Pittsburgh, PA) can be calibrated down to single-digit, micron-level accuracy over the field of view. With the extremely low thermal gain drift performance of the position transducers, complex, high-density laser machining applications will maintain consistent micron-level feature placement accuracy over the lifetime of the process.

Piezo Motors Power MRI Robot

Surgeons treating brain cancer face a conundrum: They can capture ultra-high-resolution images of the tumor using magnetic resonance imaging (MRI) or they can use ultra-precise surgical tools to remove the tumor, but they can’t do both at the same time. At least they couldn’t prior to the creation of the innovative MRI robot from the Worchester Polytechnic Institute team.

Wire Springs versus Machined Springs A Comparison

The first question generally asked about Machined Springs is how they compare with Wire Wound Springs. Commencing with this question, this review of Machined Springs will proceed. Wire Springs appeared early in the Industrial Revolution. They established their value immediately, and have not wavered from that most useful course. Certainly, enhancements in materials and manufacturing have been forthcoming, but the basic concept has not changed much. Spring wire coiled hot or cold with ends configured within the limits of coil wire has proven to be a very cost effective, industrial tool that exhibits elasticity within the bounds of known, engineering understanding. Uses range from deep ocean applications to man's reach into the universe. Finding a modern day device large or small, that does not benefit from elasticity, and particularly that provided by Wire Wound Springs, is a rare find.
