Abstract
A near-field detection optical component operating in transmission. It includes at least one portion () forming at least one grating () of diffraction microstructures () succeeding one another over several periods (p), this grating () being capable of converting evanescent waves (), which are established between the component and an object () located in the near field, when it reflects or emits radiation having a wavelength, into propagating waves (') by a diffraction effect during transmission through the portion () forming the grating () of diffraction microstructures (). The period (p) of the grating () being of the order of magnitude of the wavelength of the radiation.
