1. A microtiter plate for additive screening processes, comprising:

  • a bottom plate made of a material which is transparent for light and a cavity plate which is open at two surfaces facing one another and which has a matrix-shaped arrangement of cavities or wells;

    said bottom plate and cavity plate being fixedly connected with one another in a liquid-tight manner; and

    wherein the bottom plate is provided with at least one optically active layer at its surface facing the wells;

    said bottom plate having a thickness of from 0.01 mm to approximately 5 mm and having planar surfaces without structures;

    at its first surface facing the wells, a layer system being formed of at least two layers with different indexes of refraction; and

    said bottom plate being provided at its second surface remote of the wells with a coating which sharply reduces the reflectivity of this surface.
