普通的显微镜不能够分辨小于一个光学波长一半的样品特征,而近场扫描光学显微镜(NSOM)只要通过装备一个直径和距离样品的位置均小于一个波长的照明孔径,就可以获得较精细的分辨率。在现有的近场扫描光学显微镜中,信号/噪声比可能太低。本发明采用了一个带荧光尖端的探头,从而克服了现有近场扫描光 Conventional microscopes are not capable of resolving sample features less than half the optical wavelength and a near-field scanning optical microscope (NSOM) can achieve finer resolution by equipping an illumination aperture less than one wavelength at a location of both a diameter and a distance away from the sample . In existing near-field scanning optical microscopes, the signal / noise ratio may be too low. The present invention uses a probe with a fluorescent tip to overcome the existing near-field scanning light
