Upgrades are always fun, Laser-CutZ just got our new convex lens for machine. New lens allows better capturing of laser rays and focusing them in one point.  For end user that means that smaller beam width can be used, According to our calculations the cutting dot should now be 0.1mm comparing to old one of 0.2mm. Here is simple fact: Old lens was cutting 1/2″ armored acrylic sheet at 90% power, new lens allowed us to cust at 30% power.
