Abstract
A microlens array that corrects the problems caused by aberrations and non-paraxiality of microlenses is provided. The microlens array has a plurality of microlenses tilted a tilting degree (α, β) depending on the position of the microlens in the microlens array. Simultaneously, or alternatively, the distances Pbetween optical centres (P, P) of adjacent microlenses depend on their positions in the microlens array. Both these distances Pand the tilting degrees (α, β) are dependent normally increasing upon the distance to the center of the microlens array. The size of the microlenses may also increase with the distance to the center of the microlens array. An opaque layer may also be applied covering the edges of adjacent microlenses.
