Mad City Labs announces the introduction of the Nano-F3D lens nanopositioning system. The Nano-F3D is designed to position an objective lens in 3 dimensions with sub-nanometer accuracy and repeatability. With a travel range of 100 μm in each axis, the Nano-F3D is suitable for 4Pi microscopy as well as other imaging and inspection applications. The Nano-F3D features integrated PicoQ sensors with closed loop control, giving the user picometer precision and ultra high stability, and is designed to be mounted on microscopes and optical fixturing.
