Problems solved by technology

However, since the near-field optical microscope works in the near-field range, a very precise control system is required, the operation is complicated and requires great care, and the fiber optic probe must be replaced regularly, requiring professional technicians, and the price is also very expensive, which limits its wide application

Embodiment Construction

[0019] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0020] The super-resolution slide / cover glass structure is shown in Figure 1, which is fabricated by conventional vacuum sputtering technology. The optical nonlinear layer is a 15nm-thick gold (Au) particle film, which functions as a fiber optic probe with nanometer-scale optical apertures in near-field optical microscopy. Dielectric protection outer layer is 40nm thick ZnS-SiO 2 (ZnS and SiO 2 The chemical ratio is 1:1) dielectric film, which is equivalent to the method of controlling the distance between the fiber optic probe and the sample surface in the near-field range in the near-field optical microscope. The dielectric protection inner layer is 170nm thick ZnS-SiO 2 (ZnS and SiO 2 The chemical ratio is 1:1) dielectric film, and the substrate is a common slide / cover glass. The sample to be observed (100nm polystyrene polymer beads) is placed on the di...

Abstract

The present invention relates to micro imaging technology, and is especially member and method of realizing the micro imaging of Rayleigh resolution limitation in nano level. The glass slide / cover glass consists of substrate, protective inner dielectric layer, optical non-linear layer containing nano particle and protective dielectric layer, the nano particle has negative dielectric coefficient real part, and the protective dielectric layer is towards the sample. The combination of the super-resolution glass slide / cover glass and common optical microscope can reach effect similar to that of a near field optical microscope, and the glass slide and the cover glass may be used alone or simultaneously. The observed sample is set between the glass slide and the cover glass and set on the sample stage of a common optical microscope, then the spatial resolution of super-Rayleigh resolution limitation may be obtained in the observation.

Description

Technical field: [0001] The invention relates to an optical microscopic imaging technology, in particular to an optical microscopic imaging component and method capable of realizing super-Rayleigh resolution limit for nanoscale samples. Background technique: [0002] General optical observation instruments work in the far field, that is, measure or observe in a range much larger than one wavelength. It cannot avoid the interference and diffraction effects caused by the fluctuation of light, so its spatial resolution is limited by diffraction. limit (or Rayleigh resolution limit, ie 0.61λ / .N.A, where N.A. is the numerical aperture of the imaging system). Therefore, in the observation range of the far field, to obtain high spatial resolution, generally use: ① short-wave light source, such as ultraviolet light, X-ray or even electron beam; ② high refractive index medium, such as oil immersion objective lens; ③ high N.A the objective lens. However, the improvement of spatial r...
