EMPOWERING
OPTICAL
SPECTROSCOPY

Introducing a new line of optical spectroscopy instruments and software for a complete solution in materials characterization and research in multiple fields.

PORTO
SYSTEM

Diffraction UNLIMITED optical imaging

The Porto is a novel and versatile platform for micro- & nano-Raman and luminescence spectroscopies, based on a scanning near-field optical microscope (SNOM), achieving diffraction-limited optical spatial resolution in the micro configuration, and 10 nm in the nano configuration, in ambient conditions. Porto is engineered from the ground up for stability, maximized optical signal, and ease-of-use.

IMPACTFUL
PUBLICATIONS

Driven by a Porto TERS System, researchers from Japan, USA, Belgium & Brazil proved possible, for the first time, the use of optics, to probe the vibrational modes of a reconstructed lattice of twisted bilayer graphene, below the magic angle. Such achievement earned the team the cover of Nature journal.

The study of graphene and MoS2 homojunctions using a Porto TERS System also achieved high recognition by The Journal of Physical Chemistry Letters, portraying the article on the issue's cover.

Porto was also used to study inflammatory processes in brain tissues induced by amyloid plaques; doping characterization, mechanical deformations, and the impact of the substrate in bidimensional materials; plasmonic properties of nanostructures; nanometrologyspatial coherence length in GaS;  electron-phonon interaction; graphene defect metrology.
