摘要： The near-field spectrometer 10 comprises a Z-axis scanner 18, 20 for bringing a sample 24 and the tip of a probe 12 close to each other at a predetermined distance within a near-field 26 region when obtaining near-field spectral information and separating them from each other at a predetermined distance outside a near-field 26 region when obtaining back ground spectral information, and a data processor 22 for obtaining the true near-field spectral information free from the background by subtracting the background spectral information from the near-field spectral information, characterized in that a background information collector, during the separation of the sample 24 and the tip of the probe 12 at a predetermined distance outside the near-field 26 region, obtains the background spectral information for the corresponding portion to be measured.
