Abstract
Abstract The present invention relates to a device (1) for focusing and blending a laser beam (2) on a work surface (3), the said device (1) comprising a pair of concave mirrors (8, 9), the first (8) of which reflects the incident laser beam towards the second (9) which, in turn, directs the beam (2) towards the said work surface. Furthermore, each mirror (8, 9) is turned by a respective motor (14, 15) round an axis other than the axis of symmetry of the mirror (8, 9) itself.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
1) - Device (1) for focusing and blending a laser beam ( 2 ), characterised by the fact that it comprises : - at least a first and second mirror (8, 9), each having a concave reflecting surface (10, 11 ), the laser beam for focusing and blending being directed on to the said first mirror (8) and reflected on to the said second mirror (9) from which it is directed on to a work surface (3); - drive means ( 1 4, 15) for turning each of the said mirrors (8, 9) round an axis other than the axis of symmetry of each of the said mirrors (14, 15).
