When scanning with a laser it is a familiar problem of illuminating a line uniformly using a dot laser. To date, customers have used round Top-Hat elements as DOEs for the purpose of creating a homogeneous line; however, this has always led to a decrease in the distribution of intensity at the edge across the width of the line.
The M-shaper is a different story. LASER COMPONENTS presents the DOE that is perfectly suited for a high homogeneity in all directions. This diffractive optical element changes the laser beam in such a way that the intensity at the edge (flanks) is higher than in the center of the element.
To put it another way: If the M-shaper is used to scan across a line, then the beam quality of a Top-Hat element will be achieved - both in length and width; this results in optimal scanning performance! Neither with refractive nor with reflective elements can this be achieved.
Fifteen different standard designs are available; naturally, custom solutions to meet special specifications are available.
