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.

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.
