What is the framerate of the Pyrocam IV?

25/50Hz chopped mode, SS-100Hz pulsed mode consecutive, up to 1kHz pulse mode non-consecutive
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 Pyrocam IV?

1.6mm - 25.1mm
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.

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. 阅读更多...

Laser Beam Diagnostics in GHz Applications

When working with exotic optical wavelengths and unusually low average powers, relying on one standard measurement technology is typically not sufficient. Each technology can offer advantages, but also has limitations. Using multiple measurement technologies is often the best approach to validate results with a level of high confidence. 阅读更多...

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... 阅读更多...

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 阅读更多...

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. 阅读更多...

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)... 阅读更多...

Installing the Pyrocam III

Included below are helpful hints for installing the Pyrocam III, particularly in Windows 7.  Note; in general we recommend to not use 4-pin on-board 1394 FireWire ports (that can be found on some laptop computers) since they tend to be less reliable and/or cause the Pyrocam III to freeze when running. Instead we recommend using 6-pin plug-in adapter FireWire cards that support the 1394a 400MBS protocol used with the Pyrocam III. In newer Laptops with only ExpressCard slots, a 1394b 800MBS ExpressCard Adapter with a 9-pin FireWire connector can be used as long as you use a 9-pin to 6-pin 阅读更多...
