Modular 3D Laser Raman Microspectroscopy System Nanofinder FLEX Modular 3D Laser Raman Microspectroscopy System Nanofinder FLEX

Overview

Nanofinder®FLEX is fiber type confocal Raman microspectroscopy system with high sensitivity, high 3D-spatial resolution. This system allows users to take Raman mapping images with sub-micrometer resolution within short time. Each module (excitation laser, Raman optical unit, spectrometer) are coupled with optical fibers that make system layout flexible and compact. Typically the system comes with an up-right microscope. Piezo-stage or (and) step-motor scanners are available for fast sample mapping/positioning.

“Line Scan option” – Safe measurement for sensitive samples

・Focusing laser beam in line to decrease power density and prevent sample damage.
・Simultaneous collection of Raman spectra from many points along the laser line.
・Easy switching between traditional Point Scan and innovative Line Scan modes with integrated slider.
※Available for:Nanofinder®FLEX2 ・Nanofinder®FLEX(soon)

Application example: Li-Ion batteries

“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.
