ABSTRACT:
A stage projector extends along a first axis and is provided with a first optical system having a first focus and designed substantially to generate and concentrate a light beam in the first focus, and a second optical system set downstream of the first focus and having a second focus, the second optical system having a first optical assembly, set in a given position along the first axis so that the second focus coincides with the first focus, and a second optical assembly, selectively mobile between an operative position, in which the second optical assembly intercepts the light beam between the first focus and the first optical assembly, and a position of rest, in which the second optical assembly does not intercept the light beam, the first and the second optical assemblies being mobile along the first axis in order to modify the form of the light beam and obtain a homogeneous distribution of the light within the light beam, when the second optical assembly is set in the operative position.
