  • Photon Awarded Patent for Beam Profiling Instrument
Jun 2008
Photon’s Platen Profiler, which laser printer manufacturers use to build laser printers and printing engines, has officially been awarded Patent No. US 7,366,382. Laser printer optics are designed to produce uniform beams over the printed page, and thus, the correct alignment of the laser printer optics is critical to the clarity of the printed image. These measurements are usually performed in a static situation, where the printing engine is off, and the beam analysis is performed manually. The Platen Profiler analyzes the beam of a laser printer at multiple locations simultaneously, while the laser printing engine is activated, and provides real-time information on laser printer optical performance. In addition to performing the measurements much faster than manual methods, it replaces several separate beam profiler systems used manually with one integrated instrument. The Platen Profiler measures beam profile parameters such as beam diameter, centroid, and beam power at up to sixteen locations. From these multiple locations, laser printing metrics such as scan jitter, scan bow, linearity, polygonal mirror facet-to-facet tilt are obtained. Photon is located in San Jose, California, and is a supplier of beam profiling solutions.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
