The scanning near-field optical microscope (neaspec).
* Key features: high spectral resolution(～7cm-1 for Mid-IR, 0.5cm-1 for Raman), compatibility for multi-waveband(visible, near-IR, Mid- IR), high spatial resolution(XY：1nm, Z：0.1nm)
* Demonstration: AFM topography, SNOM mapping, nanoFT-IR, nonlinear optics, and ultrafast near-field optics
