GREEN LASER FOR BACKLIT GRAPHIC MARKING

Another application for laser glass marking is to remove an opaque coating substance—paint, for example—from a glass surface in order to backlight the laser-removed areas. Depending on the coating, you can use many different laser wavelengths—from IR to UV—for this application. Wavelengths that are absorbed by the coating but transmitted by the glass are ideal. Lasers can remove graphics, text characters and even data matrices without damaging the glass.
