Specifications include, but are not limited to:System Specifications: The system should include following specs: • <1m Diffraction limited optics • User selectable detection laser source and spot size – made for small cantilevers • Atomic resolution imaging in closed loop operation • Truly modular scanners – The entire XYZ scan unit is a module • Unprecedented drift control/ stability The system should meet the following specifications: • Deflection Noise: <20pm • Bandwidth: DC to 7MHz standard • Spot Size: User selectable and exchangeable. Both RF modulated laser diode (LD) and low coherence super luminescent diode (SLD) light sources are available with focused spot sizes of 10x30m or 3x9m for optimum performance with each cantilever and research application. • Controls: Laser spot positioning and photodiode detector centering controls are motorized and fully controlled through the software. Automatic alignment allows the user to simply click on desired location of the cantilever for the laser spot and the software controls the motors to position the laser. In addition, the photodiode signals are automatically centered.
