| Patent Number: |
8002439 |
| Title: |
Stage Projector |
| 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.
