A new laser machine technology for selective cactus spines elimination was created. The machine automatically “finds” the spines by using optical detection and eliminates them without damage to the substrate. Each cactus is cleaned in 5-10 seconds preserving the product properties thanks to real-time optical monitoring of ablation process.
