Holo/Or has developed a hexagonal multi-spot array with square edges, which it will be demonstrating at the show in San Francisco. The optical array was made for aesthetic laser dermal treatment.

Traditionally in this application, laser light is split using diffractive optics into multiple spots that create an array of micro-scarring on the skin. These invisible micro scars create tension that eliminates creases from the skin, rejuvenating it and improving its appearance.

Normally, diffractive optical elements used for this purpose have a square lattice of spots, thus each spot has four near neighbours. Holo/Or’s hexagonal multi-spot array gives a more even distribution of spots, with each spot having six near neighbours, thus potentially improving the treatment uniformity.
