Overview

Nanofinder®30 is a Raman Confocal spectroscopy device with high sensitivity and high spatial resolution. It can do 3D Raman imaging with lateral spatial resolution of 200 nm and axial resolution of 500 nm. Moreover, combined with Scanning Probe Microscope (SPM), it can perform simultaneously measured Raman and Topography Imaging. With Tip Enhanced Raman Scattering (TERS) technology it can obtain lateral resolution of 50 nm or less. With UV excitation, it is ideal for Si device stress distribution measurement.

“Large Area Scan option” – Fast mapping of big samples

・Raman mapping with step motor stage of millimeter, centimeter or even larger scanning area.
・Fast scan by synchronized constant speed sample movement and data collection.
・Easy switching between point scan and fast scan.
・Combinable with “Line Scan” option.
※Stepping motor stage is required for this scan option.
