The invention discloses an achromatic weak measurement wavefront sensor which divides light into a positive diagonal component and a negative diagonal component and ensures that the relative positions of the light of the two components are horizontal and vertical after displacement. After passing through the Savart sheet, the light of the right opposite angle component and the light of the reverse opposite angle component are both subjected to one-time displacement and one-time non-displacement, so that there is no optical path difference between the light and the Savart sheet theoretically. In cooperation with an achromatic phase delayer, the weak measurement wavefront sensor provided by the invention can be suitable for monochromatic light with wavelengths in a certain range, and when the weak measurement wavefront sensor is used, l corresponding to the wavelength is inquired according to a dispersion relation. The applicable wavelength range is mainly determined by the applicable range of the achromatic wa
