DPSS Lasers Inc. (Santa Clara, CA, US) showcased, at CAMX 2014, laser systems designed to mark and ablate a wider range of materials, including plastics and composites, by handing out pens to visitors that had just been inscribed with the visitors’ names. Its Samurai marking system, the company claims, is the first designed for UV lasers that operate at 355-nm wavelengths. The system reportedly takes advantage of this shorter wavelength to prove a smaller “spot” size (laser beam contact area as low as 6 micrometers) and a large depth of focus. Laser markers take advantage of “cold” marking that does not require high power output and enables marking without damage to sensitive substrates. The marking system is also capable of UV ablation (e.g., burning off unwanted contaminants) and engraving (marking that removes material, creating markings that have relief). Systems features include easy-to-use software for marking preparation and machine instruction, fast scanning speeds, a large work area for large markings (up to 170 mm).
