Latest Patents

One of Helman's latest patents is titled "Method and apparatus for laser scribing glass sheet substrate coatings." This invention outlines a method and apparatus for laser scribing coatings on glass sheet substrates. The process involves conveying the substrate adjacent to a laser source that emits a pulsed laser beam with a wavelength at a near-infrared fundamental frequency. The laser operates within a frequency range of 50 to 100 kilohertz and has a pulse duration between 8 to 70 nanoseconds. The beam is reflected by an XYZ galvanometer-controlled mirror system toward an uncoated surface of the substrate, allowing it to pass through to the coating on the opposite surface. This innovative method provides overlapping ablations through the coating and enables scribing at a speed of at least 1000 millimeters per second.
