    This article reports the measurement results acquired when a metal sheet was scanned with a resolution chart engraved on its surface.

  7. Intro To Laser Management: Laser Profiling 101
    1/25/2017

    Traditionally, laser operators only verify a laser’s average power or energy to improve efficiency and, if everything is in order, put their laser back into service. This article discusses steps required to identify and use a camera profiling system (arrayed camera, attenuator, and beam dump) for laser management.

  8. Reducing Production Waste With Laser Profiling And Characterization
    1/25/2017

    A critical component in a laser manufacturing process is the understanding of which process parameters or key control characteristics must be measured and how they will relate to product quality and waste. A laser profiling system can be a great benefit for characterizing and identifying which variables affect product quality and waste minimization. Unfortunately, many companies realize this too late and incur more expenses and extended downtime than necessary when trying to implement the system near the end of the process. This article dives into a method of using in-house tools, like laser profiling, to characterize and optimize a process in advance so that product quality and process variability may be understood and maintained.

  9. Utilizing A New Autofocus Technique For Laser Systems With Optimet's Non-Contact Distance Sensors
    11/30/2016

    Many of today’s conventional marking, welding, drilling, and cutting laser systems have the challenge of focusing the laser accurately on the object’s surface. As the demand for faster and more precise manufacturing processes increase, the need to control the focal point of a laser becomes much more critical. This application note discusses a new laser measurement method that integrates Optimet sensors into laser systems, offering the benefits of autofocus capabilities while upgrading a number of system performances.

  10. Materials Processing: When Laser Measurements Absolutely, Positively Must Be Made
    11/30/2016

    In order to improve laser-based processes, a variety of parameters must be measured to understand how design changes effect performance, and how to help avoid component degradation. The challenge occurs when figuring the proper frequency of measurements throughout the life of the laser, choosing which measurements should be tracked, and what should be done with the collected data. There are five times within a laser system’s lifetime where the collection and application of laser performance measurement data are critical to the process’ outcome.
