A microscopical imaging system for the widefield microscopical imaging of a sample. The imaging system includes a ray path with an objective, a tube lens system arranged behind the objective as seen from the sample, and a relay optical system with an objective-side component and an image-side component. The objective-side component includes at least one first objective-side lens group and a second objective-side lens group. The image-side component includes at least one first image-side lens group and a second image-side lens group. The relay optical system transfers an image of the exit pupil of the objective to a pupil plane between the objective-side component and the image-side component. The relay optical system transfers an image of the sample from an intermediate image plane to an image plane. The imaging system includes an adaptive optical element that is arranged at the pupil plane between the objective-side component and the image-side component.

Microscopical imaging system

The invention is directed to a spectacle lens and includes a body which is transparent or at least partly transparent to light and has a phase object which guides the light incident at an angle of incidence &#x3b1; on a side facing away from an observer into a direction depending on the wavelength &#x3bb; of the light and the angle of incidence &#x3b1; thereof. The phase object has a multiplicity of diffraction structures, which diffract monochromatic light at a wavelength of 380 nm&#x2264;&#x3bb;&#x2264;800 nm with a diffraction efficiency of &#x3b7;&#x2265;70% into one and same order of diffraction |m|&#x2265;1 when the monochromatic light is incident at an angle of incidence &#x3b1; on the side of the lens facing away from the observer which lies within a diffraction-structure-specific angle interval 15&#xb0; wide and dependent on the wavelength of the light.
