Porto-SNOM nanoscope


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.

Porto-Core Highlights

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.

Remote operation

Fully operate the equipment remotely after placing sample.

Porto-SNOM Highlights

Resonant tips

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.

Correlative Microscopy

Easily co-localize optical, SPM and SNOM measurements using the streamlined laser-tip alignment tools.
