The Porto line is a novel and versatile scanning near-field optical microscope (SNOM) system built from the ground up to provide an ease-of-use experience, with a fast-learning curve, while providing a high spectral signal intensity and diffraction UNLIMITED spatial resolution.
The Porto line-up consists of the Porto-Core system, capable of micro-Raman and other spectroscopy techniques, as well as the Porto-SNOM addon, which expands the Porto Core for nano-Raman measurements based on the TERS (tip-enhanced Raman spectroscopy) technique. Porto delivers unprecedented Raman signal enhancements, while also providing an innovative control software and powerful never seen analysis tools.
Modern control and analysis softwares
Real-time hyperspectral image processing capabilities on a user-centric, customizable interface.
Open optics design
Optional access to excitation and collection paths, for maximum customizability in your research.
Fully operate the equipment remotely after placing sample.
TERS tips, using PTTP technology, provides optical signal enhancement in the order of 80x on 2-D materials (when comparing Raman intensity with and without the presence of the PTTP).
High Sensitivity non-contact AFM
The shear-force AFM implemented in Porto system enables imaging delicate samples with high precision, while also capting capturing spectral data.
Easily co-localize optical, SPM and SNOM measurements using the streamlined laser-tip alignment tools.
