    What is the framerate of the SP920G?

    14 Frames/second

    The effective frame rates listed in BeamGage specification sheets are the maximum rates typically achievable in actual use.  Frame buffering, image processing techniques, graphical displays, and mathematical computation all add degrees of overhead to achieving higher frame rates.  This can be further limited by the available PC hardware.  BeamGage features two modes, Frame Priority and Results Priority, which change how the system balances the work.  Results Priority acquires a frame, performs any enabled image processing, performs all calculations and updates the graphical displays before accepting another frame from the camera.  This mode is most useful when a temporal sequence of frames is not necessary and should always be enabled when logging.  Frame Priority mode will allow the calculations and graphical display updates to be interrupted if another frame is ready from the camera before those operations are complete.  This can be useful when collecting all frames at the maximum camera frame rate is necessary.

    What beam sizes can I measure with the SP920G?

    44μm - 5.3mm The accurate beam size minimum is derived by the pixel size of the camera. In order to get an accurate measurement, there must be enough coverage of pixels to ensure that illuminating another pixel will not over exaggerate the beam size.

    This step-by-step tutorial will show you how to set up a camera-based beam profiling system on an industrial single-pulse laser welding system.
    It will also demonstrate for you how to simultaneously analyze the laser's focused spot, measure the laser's energy per pulse, and measure its temporal pulse shape.

    How to Design Your Perfect Laser Beam with BeamMaker How to Design Your Perfect Laser Beam with BeamMaker How to Design Your Perfect Laser Beam with BeamMaker

    BeamMaker helps engineers, technicians, and researchers understand a beam's modal content by subtracting theoretically generated modes from real beam measurement data. Derive a perfect beam profile by specifying the mode, size, width, height, intensity, angle, and noise content - then comparing it to theoretically derived measurements. The end result is knowledge about how much the real beam varies from the desired beam.

    Apples to Apples: Which Camera Technologies Work Best for Beam Profiling Applications, Part 1

    In 1997, Dr. Carlos Roundy, founder and president of Spiricon Inc., presented a paper at the 4th International Workshop on Lasers and Optics Characterization in Munich Germany. This paper was based on work that was carried out at Spiricon in the mid 90’s. At the time new insights were being presented on how to characterize a laser beam. Previous definitions were somewhat simplistic and most often were driven by customers telling us how they wanted the beam measured. Read more...

    Ensuring Quality Welds in Medical Devices

    Many customers involved with laser welding measure the pulse energy output of their lasers, but is this all the data required needed to ensure quality welds? Steve Schellenberg at Spinal Modulation had his doubts. While he found pulse energy measurement using his Ophir equipment useful in qualifying his laser welding process, two of his laser welding stations were producing different quality welds despite producing identical laser pulse energies. One laser welder seemed to be doing an OK job, while the other welder produced significantly lower quality welds. Steve suspected differing laser Read more...

    Customers that purchase the above items also consider the following items:
    • Optical Camera Trigger
      The Optical Camera Trigger is an optical sensor that detects pulsed light sources and generates outputs to trigger a camera. The front aperture of the Optical Trigger must be directed at a light source that provides the necessary properties for trigger activation. (e.g. a laser flash lamp, a pick-off source from the main laser beam, or similar).
