What is the framerate of the SP1201?

60 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 SP1201?

300μm – 7.4mm
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.

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. 阅读更多...

Using the built in photodiode trigger on the SP620U and SP503U cameras.

With the introduction of BeamGage the capability of using the built in photodiode trigger in the SP camera series is now available. However, some customers may not know how to use it or that they even had this capability. With the recently released BeamGage version 5.4 this capability is now available. Some cameras may need to have their firmware upgraded where others just need to update to the latest version of BeamGage. To see if your camera has the latest firmware make sure you are using BeamGage 5.4 and connect your camera to the computer. Launch BeamGage and when it opens click on 阅读更多...

  • 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).
