Abstract

A microscope with sub-wavelength resolution with a light source for monochromatic light with a predetermined wavelength, an object carrier for an object to be examined, and an image sensor with an optical structure with a first side and a second side opposite to the first side, the optical structure having a negative refractive index, and a pixel array extending along the second side of the optical structure at a predetermined distance, wherein the first side of the optical structure of the image sensor is arranged at a near-field distance smaller than the wavelength of the monochromatic light to the object carrier.
