FAQ

What is the distance from the front of the camera to the sensor?

We call this term a "CCD recess". Ophir provides differen Beam Profiler cameras designated for varies uses , thus there are 2 types CCD recess: Most models has 4.5mm CCD recess. Some models have standard C-mount camera has a sensor depth from the front of the camera to the sensor of 17.5mm. Some outdated Ophir beam profilers had 12.5mm recess.

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.

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. Read more...

LIDAR Guns, Accuracy, and Speeding Tickets

Anyone who has driven a vehicle has encountered a Light Detection and Ranging (LIDAR) system in action. Some of you have even found out how much it can cost in terms of speeding fines! Let’s take a closer look behind the scenes. How do we know the detector is working? Read more...

BeamGage Professional partitions with multiple beams on one display with individual results.

The Partition feature, available in BeamGage Professional, allows subdividing the camera imager into separate regions, called partitions, and which can then compute separate beam results within each partition. Read more...

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.  Read more...

Imaging UV light with CCD Cameras

Is it possible to image a UV laser with a Silicon Sensor CCD camera offered by Ophir-Spiricon? The answer is yes, but the direct UV light ablates Silicon CCD chips over time. The ablation is cumulative and depends on the intensity, the wavelength, and the duration of the light on the sensor. The best choice for imaging UV light without damage is to avoid directly imaging the beam on the CCD sensor by using an UV image converter... Read more...

Understanding Dynamic Range…The Numbers Game

There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this applications note is to explain some of the terminology used in the discussion of this parameter by both Ophir- Spiricon and other suppliers of beam profilers. DefinitionDynamic Range is the ratio of the largest measurable signal to the smallest measurable signal. The smallest measurable signal is typically defined as that equal to the noise level, or alternatively the “Noise Equivalent Exposure” or that point where the Signal-to-noise ratio (SNR) is 1. To Read more...

The Focal Length Divergence Measurement Method

The Focal Length Divergence measurement method is based upon the beam width of a focused beam’s spot size and the focal length of the focusing optic. The Focal Length Divergence method provides a means for finding the far-field beam divergence at any point in the beam propagation path. As shown below, the calculation performed by the BeamGage® software is quite simple; however the optical setup must be done with great care. Read more...

Laser Beam Measurement Vocabulary

Wavelength: In physics, the wavelength of a sinusoidal wave is the spatial period of the wave— the distance over which the wave's shape repeats,[1] and the inverse of the spatial frequency. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns.[2][3] Wavelength is commonly designated by the Greek letter lambda (λ)... Read more...

  • 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).
