NFS-230/330 Nearfield Spectrometer

The NFS-230/330 Near-field Scanning Optical Micro-photoluminescence spectrometer and is a new kind of micro-spectrometer for observation of photoluminescence/Raman and fluorescence spectra at sub-wavelength high-spatial resolution.

Spectra and spectrally resolved mapped images can be obtained from single semiconductor quantum dots and wires at better than 100nm spatial resolution.

Metals, semiconductors, plastics and biological materials can be examined and sample preparation is unnecessary.

Images can be generated by both topographically (optical contrast and probe feedback) and PL emission spectral mapping from the near-UV to NIR wavelength range. The NFS-230 can actually map a sample within the area of a single micro-Raman confocal laser spot with better than 0.5 cm -1 spectral resolution.

JASCO’s purpose-designed, computer-controlled optics integrate the scanning probe, laser and spectrometer / detector in a complete, stand-alone system. Peltier cooled CCD detector option allows rapid instrument start-up and low running costs with high sensitivity. A wide range of sample environments can be used for in-situ observations. Standard configuration is for room-temperature spectroscopic measurement (NFS-230). For ultra-low temperature (~5K) the NFS-330 is the first commercial helium cryostat equipped NSOM system. The JASCO aperture fiber probe near-field system allows various optical arrangements for illuminating and collecting the light from the sample. Superb quality high-throughput probes with a range of apertures are available as standard. Our probes are reproducible and guaranteed: individual SEM images of the tip can be provided. The NFS probes can be replaced quickly and easily as required. JASCO aperture NSOM probes are also available separately upon request and with short delivery times.
