Until now, many customers have used round Top-Hat elements as DOEs in order to produce a homogeneous line using a dot laser. This method however leads to a decrease in the intensity distribution at the edge, across the width of the line.
The M-shaper, however, is different! It is perfectly suited for a high homogeneity in all directions. This diffractive optical element modifies your laser beam in such a way that the intensity at the edge is higher than at the centre of the element. The cross section of the intensity distribution resembles the capital letter M, giving this product its name. Using the M-shaper to scan across a line will produce the beam quality of a Top-Hat element in both the length and the width, resulting in optimal scanning performance. These results could not be achieved using either refractive or reflective elements.
We have a range of standard, semi standard and custom designs available to ensure that your specifications are met.
