Optical Power: 450nm 2.5W CW. Beam Shape: focus 0.08x0.08mm Dot.
It supports metal engraving including alumina oxide and other non-reflective materials, depth of engraving (0.5-3mm wood), thickness of cutting (2mm). Supported engraving materials: Wood, gray paper, leather, bamboo, blackening plastics, rubber, alumina oxide, etc. It is not possible to directly engrave the metal with a strong reflective mirror, which may cause injury to the operator or burn the laser. It can be directly engraved on alumina oxide, and it is not possible to engrave other metals directly. If you need to engrave other metals, at least this metal needs an oxide coating, then it can be engraved.
