As technology has advanced laser marking, new markets have evolved to take advantage of the faster speeds and greater marking precision marking and imaging capabilities.
Marking technology available, laser marking beam-steered system provides the user with the greatest amount of flexibility images quickly, permanent process, non-contact marking. As manufacturing processes become more automated and more common after-sale tracking, laser markers are often the only method available to produce, a unique permanent image individually at high speed.

Good delivery optics consists of a simple focusing lens assembly or collimator fixed combinations and flat-field lens assembly. In both instances, the laser beam is directed across the surface of the work with mirrors mounted on two high-speed, computer-controlled galvanometers.
Simple focusing assembly offers the advantages of lower costs and fewer optical components and is used routinely with a CO2 laser.
Flat-field lenses also produce a higher power density on the surface of a simple work focuses assembly for a shorter effective focal length. Flat-field lens design is always preferred for high accuracy and high-quality images and is usually combined with the application of Nd: YAG laser.
Both designs provide the user with the option of building a second lens diameter and a wide field mark marking-line. Longer lens-focal-length provides greater workplace, but also enlarged the line width, thus reducing the power density on the work surface.
