Yes, the laser is completely safe to operate. It is a Class 2 laser - 1mW CW Maximum 600-700 nm, which means that the laser is secured with interlock devices so it will not run with the doors of the system open. No special safety gear is required to run the laser.
No, one laser does it all! Our CO2 laser systems will engrave and cut most non-metallic materials, as well as engrave coated metals. The laser can be set to engrave only, cut only, or in a combined mode. The laser knows waht to engrave and what to cut based on line width, which is easily set.
Laser light can be highly collimated by means of a focus lens. An extremely high energy density is generated in the focus of the laser beam, which can be used for melting or evaporating the material. In addition, using suitable optics (mirrors), laser light can be directed and reflected, and this completely without any losses even over large distances. Positioning systems (laser plotters) or galvanometer scanners are used as movement systems. The result is a universal and wear-free tool as the laser beam will never become blunt.
You can engrave scanned photos, logos, bitmaps, other images, text, and AutoCAD files. Essentially, if you can print it, you can engrave it. To cut, you will need a vector based graphic, such as an .eps or Illustrator file. Keep in mind the higher the quality of the graphic you're working with, the better your engraving results
