An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L) comprising a multitude of transmissive or reflective microlenses () which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array (S) of light sources () for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P=2LD/N, wherein N is an integer with N&#x2265;1. High-contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.
