State of the Art Equipment

The right tools provide the fuel for groundbreaking research. The following is a selection of equipment at the finger tips of NEOL researchers.

Modified Aurora 3 with Head Scanning
Park System cantilever based XE-NSOM
Veeco Explorer Scanning Probe Microscope (SPM) platform. This platform form features open architecture and modulo design, proving the ultimate flexible for our nanoscale imaging research. 
PHE-2 Spectroscopic Ellipsometer (200 nm - 1100 nm). 
Microellipsometer. This is a home-built equipment invented by Prof. Zhan. Currently, Mr. AlainTschimwangan is integrating the software with the hardware and testing the system.  
Spectra-Physics Tsunami fs laser (with Prof. Powers and Prof. Haus). This fs laser oscillator and the Spitfire regenerator are the work horse for our ultrafast laser applications. The system will be used for THz imaging, spectroscopy, multi-photon imaging, multi-photon polymerization and intensive laser pulse propagation studies.
