It can be termed "pico-technology" in that it goes beyond nanotechnology to control the tilt angle of liquid crystal molecules, which are only around two nanometers(4) in size, with an accuracy measured in picometers.(5)
With an adequate design this reflective coupling may be limited to a narrow spectral range, typically to a few hundred picometers.
Operated by the company's new E755 nanopositioning motion controller, they have a mechanical accuracy within 25 picometers. That's a quarter of an angstrom.
They use the latest digital single acquisition and processing technologies to achieve excellent displacement accuracy and resolution (down to 1 picometer), high linearity, and low harmonic distortion over a wide vibration frequency range.
Headquartered in Hillsboro, Oregon, USA, FEI Company designs, manufactures and supports a broad range of high-performance microscopy workflow solutions that provide images and answers at the micro-, nano- and picometer scales.
The CCD optic system with a PaschenRunge mount assembly delivers a resolution of 8.5 picometer in the wavelength range from 130 to 340 nm.
The result is the FPS3010--Real Time Interferometric Sensor, a high-bandwidth optical displacement sensor with sub-meter range and the ability to read target position variations at the picometer level.
The high sampling rate and differential measurements allow detection of protein mean height changes down to tens of picometers (1 picometer = 1/1000th of a nanometer).
