Abstract
The invention relates to a microlens arrangement () and an illumination device () for uniformly illuminating of an area (F), with a light source () and a microlens arrangement (). In order to illuminate the area (F) to be illuminated as homogeneously as possible, the at least one microlens () of the microlens arrangement () has an entrance face () which is shaped such that monochromatic light incident on the microlens () and propagating parallel to the optical axis (O) is refracted by the entrance face () such that back focal lengths (S, S, S) of the light with the optical axis (O) increase with the height of incidence (E, E, E).
