Because of their low spatial resolution due to the diffraction limit, traditional optical methods cannot be used for near-field measurements. The Near-field Scanning Optical Microscope (NSOM) was introduced to circumvent this problem [2]. WebThe index of refraction is the ratio of the speed of light in a vacuum to the speed of light in an optical medium, which describes how light slows down as it passes through the material. The refractive index for optical glasses (nd) ( n d) is specified at the Helium d-line wavelength of 587.6nm. arara de roupas taguatinga df
