LT-SNOM

Low Temperature Scanning Near-Field Optical Microscope (LT-SNOM)

LT-SNOM has the capability of near-field imaging and spectroscopy together with other AFM modes such as contact, dynamic, MFM, cAFM. A sample is illuminated optically by introducing a laser beam through specially designed optical fiber. The detected optical signal is transmitted via a fiber tip to a spectrometer. A topographic image can be obtained simultaneously with an optical image.
