Overview

General Description

Instrument is used for characterization of materials in nanoscale via near-field optical imaging, Raman and photoluminescent spectroscopy.

Can operate in different modes:

• Scattering type Scanning Near-field Optical microscopy (s-SNOM) over broad frequency range

• Point spectroscopy with PhSet.

• Tip-enhanced Raman Spectroscopy (TERS)

• Tip-enhanced Photoluminescence (TEPL)

Specifications

s-SNOM

Equipped with a mid-infrared tunable OPO laser, this instrument enables nanoscale imaging at wavelengths from 1403 nm to 17000 nm with spatial resolutions down to 20-nm.

Point Spectroscopy

Widely tunable OPO laser can shine on an AFM tip over broad wavelength range and enable both amplitude and phase spectroscopy at any spatial point of interest.

Laser output range is shown below:
