<p>A laser beamsplitter for generating a plurality of parallel beams (101, 102, 103) comprises a first beamsplitter (30) and a second beamsplitter (32). The first and second beamsplitters (30, 32) are manufactured from glass flats having precisely parallel faces, wherein the front surface (36) is coated with a reflective coating and the back surface (38) is coated with a beamsplitter coating such that an initial laser beam (99) passing through the first beamsplitter (30) at a preferred angle of incidence is split into a first beam (100) and a second beam (101). The second beamsplitter is positioned relative to the first beamsplitter such that the first beam (100) passes through the second beamsplitter and is split into a third beam (102) and a fourth beam (103).</p> |
