Fundamentals of Laser Measurement & Beam Profiling Fundamentals of Laser Measurement & Beam Profiling Fundamentals of Laser Measurement & Beam Profiling

Is your laser's beam profile shaped correctly for your application?
This video teaches the fundamentals of laser beam profiles and discusses the benefits of profiling your laser beam.
Several case studies are presented showing before and after laser beam profiles.

Measuring Laser Focus Spot Size in an industrial Medical Device Application Measuring Laser Focus Spot Size in an industrial Medical Device Application Measuring Laser Focus Spot Size in an industrial Medical Device Application

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.

White Paper – 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. Weiterlesen...

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 Weiterlesen...

Why is Test Equipment Always Suspect?

When a laser malfunctions and diagnostics begin, why is test equipment the first to be questioned for its accuracy when it was the laser that failed first ? Weiterlesen...

White Paper – ISO compliance of non-contact, real-time beam analysis

1. IntroductionDuring the past decade laser power levels used in production applications has risen significantly. Today, welding systems are commonly using laser power in the range of multiple kilowatts. To deliver continuously high product quality, the key parameters of the laser beam must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology based on the Rayleigh scattering. The technology used in the BeamWatch laser beam profilers enables the measurement of high-power beams without ever touching the laser beam. As the technology is Weiterlesen...


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).
  • Neutral Density Filters
    The individual filters come in three versions, the ND1 filter in the red housing with ~10% transmission in the visible, the ND2 filter in the black housing with ~1% transmission and the ND3 filter in the green housing with ~0.1% transmission. The individual filters can be screwed on top of each other and thus stacked. They are set at a small wedge
  • LBS-300 Attenuator
    The LBS-300s beam splitter attachment for C-mount, CS-mount, or Ophir mount cameras allow you to measure laser beams with diameters
  • CCTV Lens
    When direct imaging in front of the camera, like imaging an image projected onto a defusing surface, like a ground glass plate, it is necessary to reduce the image so that it completely fits onto the CCD chip surface. The 25mm and 50mm CCTV lenses image an object from a given plane in front of the lens onto the CCD while reducing the size.
  • Near field profiling can also be used with camera profilers to analyze small beams, and involves a microscope objective lens to image the beam onto a camera detector array. This technique expands the measurement range of the camera to include smaller beams, which could not be ordinarily measured due to the pixel size of the detector array. Near
  • 4X Beam Reducer
    The 4X Beam Reducer is an imaging system that images the plane 30cm in front of the reducer onto the camera CCD sensor while reducing the size 4 times and inverting it. The beam reducer uses the 3 screw on attenuators provided with the camera. Since the intensity of a beam after reduction will be increased by 4x4=16 times.
  • 4X UV Image Reducing Converter
    The UV image converters are fluorescent plates that convert UV radiation that is poorly imaged by silicon cameras into visible light that is then imaged onto the CCD of the camera. These fluorescent plates are specially designed for UV conversion and have a high light output, wide linear dynamic range and high damage threshold.
  • 4X Beam Expander
    Beam expanders are designed to work with C-mount threaded cameras that have 4.5mm imager back focal spacing or with CS (12.5mm) back focal spacing. The 4X beam expander is an expanding telescope that images the beam as it looks at 8mm from the end of the expander onto the CCD while enlarging the image 4X.
  • Microscope Objectives
    Microscope objectives are available for expanding the beam even more. There are objectives for 6X, 12X, and 22X expansion. The various expanders allow the use of our 2% and 10% filters as well as the variable attenuator so as to accommodate the camera to a wide range of source intensities.
  • Stackable Prism Front-Surface Beam Samplers
    The Prism Front-Surface Beam Sampler (PFSA) is a C-mount fixture housing a UV-Grade Fused Silica right angle prism, used for sampling the front surface reflection for high power/energy beam-profiling applications. Reflection at nominal incidence of 45°is polarization and wavelength dependent, with 532nm s-polarization reflected at 8.27%, and p
  • Stackable Beam Splitters
    The stackable beam splitters are designed for maximum modularity and shortest beam path. They are compatible with almost all of our cameras having the standard C mount thread and can mount either to other attenuators or to the camera itself.
  • Beam Tap I & II
