Lenox Laser offers different standard or custom shapes of patterns. Negative or positive marking on most opaque and transparent materials are readily available and produced. Marking a periodic structure such as a set of lines spaced with variable or constant period on a surface turns the material into grading or optronic crystal. The efficiency of these devices highly deepens the accuracy and precision of the manufacturing process. It is for this reason the Lenox Laser engineering and production teams are constantly improving their tools and processing methods.
