All complex and intricate assemblies include components with natural frequencies that are critical because they exist in the generalized 8 to 200 Hz environmental spectrum. This can be demonstrated by ...

There are natural frequencies in all equipment that have components. Generally, they exist in the 8 to 200 Hz environmental spectrum. Figure 46.1 demonstrates the transmissibility and resonant ...

Unwanted vibrations can misalign optics and cause images to blur. Jacqueline Hewett discovers how optical tables and vibration isolation systems can solve the problem. All buildings vibrate, whether ...

Lasermet and NPL (the National Physical Laboratory) have produced this joint venture product, Optoblok, the latest safety equipment for use in optical laboratories. Optoblok, the Optical Table Laser ...

In recent years, the push to foster increased technological innovation and basic scientific and engineering interest from the broadest sectors of society has helped to accelerate the development of do ...

When you’re talking about optics, things are often happening on a nanometer scale. This means that even the slightest amount of vibration can spoil delicate work. [The Thought Emporium] is working on ...

WASHINGTON — Researchers have developed a way to create freeform optical components by shaping a volume of curable liquid polymer. The new method is poised to enable faster prototyping of customized ...

A new technique can assemble optical and electronic components separately on the surface of a computer chip, enabling the addition of optical components to existing chips with little design ...
