Gravitational Waves Detected 100 Years After Einstein's Prediction
“For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe.  This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos. Gravitational waves carry information about their dramatic origins and about the nature of gravity that cannot otherwise be obtained.  Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole.  This collision of two black holes had been predicted but never observed.”

Mad City Labs congratulates the LIGO scientific collaboration on their discovery, which will open new avenues of astrophysical research. Advanced LIGO uses Nano-MTA2 fast mirror steering nanopositioning systems as part of their auxiliary optics subsystem. The Nano-MTA2 is the lowest position noise beam steering system available.

The Nano-MTA Series
The Nano-MTA Series are single axis and two axis piezo nanopositioning mirror tip/tilt actuators. With nanoradian resolution, the Nano-MTA Series is ideal for applications involving laser beam steering, tracking, and scanning. Internal position sensors utilizing proprietary PicoQ® technology provide absolute, repeatable position measurement under closed loop control. The Nano-MTA Series is compatible with either the Nano-Drive® or Nano-Drive®85 controllers. Both controllers include sensor electronics, proportional integral feedback control, and 150V amplifiers. When used with the high power Nano-Drive®85 controller, the Nano-MTA Series is capable of continuous, high speed scans at 400 Hz and step response times down to 2 milliseconds.

Mad City Labs, Inc
Mad City Labs, Inc has been a leading manufacturer of flexure based piezo nanopositioning systems capable of sub-nanometer positioning resolution since 1998. Our piezo nanopositioning product line covers the entire spectrum of piezo nanopositioning capabilities while maintaining a leadership role in multi-axis stages for high speed optical microscopy imaging. Mad City Labs engineers use 3D CAD and finite element analysis to produce piezo nanopositioners which combine long ranges of motion with exceptional linearity, orthogonality, and stability. Our in-house CNC machining centers and wire EDMs provide complete control of mechanical assembly production and allow Mad City Labs to design and fabricate custom systems with minimal engineering costs and short lead times. We deliver the tools for nanotechnology in 30 to 45 days and provide the highest level of customer service and satisfaction in the industry. We provide innovative and practical solutions for today’s demanding biotechnology and nanotechnology applications. Most Mad City Labs piezo nanopositioners can be controlled by our high speed USB 2.0 interface. Applications for nanopositioners include super resolution microscopy, high speed confocal imaging, AFM, NSOM, scanning probe microscopy, fiber positioning, single molecule spectroscopy, single molecule/particle tracking, high resolution optical alignment, SR optical microscopy, sub-diffraction limit microscopy, nanoscopy and lithography.
