Optics & Photonics
Adjusting optical lenses for zooming and focusing or the adjustment of mirrors in laser applications require maximum precision in the smallest possible installation space. Here, FAULHABER drive systems provide full functionality in compact form.
When Wilhelm Röntgen discovered and investigated the X-ray in the late 19th century, he was one of the few pioneers in the field who routinely used protective lead shields. He may not have known the precise reasons why, but he suspected that this kind of radiation was not good for human health – and his suspicions were well founded. Despite this, X-rays help to restore health as they are one of the most powerful instruments in medical diagnostics and, in many cases, are crucial for identifying the right course of treatment. When it comes to achieving the best imaging with the lowest possible X-ray dose, lenses made by Italian company Optec are almost inevitably involved. Their aperture, focus, filters and zoom are moved by FAULHABER motors.
If you turn on your pocket torch for just a second and point it towards the sky, your beam reaches all the way to the moon. How fast would you need to switch the torch on and off in order for the beam to be shorter than the thickness of a human hair? It's not something you could accomplish with your thumb, that much is certain. Ultra-short beams, or pulses, of this order of magnitude are emitted by so-called femtosecond lasers, which split the laser light into compressed, high-energy wave packets. They can be used to work on any material – from the cornea of the human eye to super-hard ceramics – with micron accuracy. The French manufacturer of precision devices, ISP System, produces the actuators with which the prisms, mirrors and fi lters in such high-performance lasers are precisely aligned so that the light pulses reach the right point with the right power. Reliable drive is ensured by the stepper motors from FAULHABER.
