Pyrocam IIIHR Beam Profiling Camera

Gen 3 High-Resolution Broadband Pyroelectric
Array Camera with BeamGage

The Pyrocam camera accurately captures and analyzes wavelengths from 13nm - 355nm and 1.06-3000µm with its broadband array. It features a solid state high-resolution array with a wide dynamic range, fast data capture rates, and operates in CW or Pulsed modes which makes it ideal for analysis of NIR, CO2, and THz sources.

  • BeamGage ProfessionalBeamGage Professional
    BeamGage Professional has all of the functionality that BeamGage Standard includes. BeamGage Professional supports all of our beam profiling cameras, includes window partitioning to allow analysis of multiple beams on a single camera, and includes an automation interface written in .NET to push data to your custom applications.



What is the dynamic range with the Pyrocam III, CCD's, or various other cameras?

  • CCD camera manufacturers typically quote a signal-to-noise ratio of 50 to 60db. This refers to the peak signal before saturation divided by the RMS noise. This is a 20 log function, so 60db would be equivalent to a dynamic range of 1000, whereas 50db would be a dynamic range of about 300. However, it should be noted that this is comparing peak signal to RMS noise. The peak-to-peak noise is about 6 times the RMS noise. Therefore, the dynamic range in terms of peak signal to peak-to-peak noise ranges from about 50 to 180. With 8-bit digitizers, i.e., 256 counts, this means that the bottom 2-5 counts in the digitizer are noisy.
  • The Pyrocam III pyroelectric camera also has a 60db signal-to-noise ratio. However, this is a worst case pessimistic specification. Typically the dynamic range is about 70db, which means the dynamic range is about 500 relative to peak-to-peak noise. This makes the camera very useful with 10 and 12-bit digitizers

How do I get the Pyrocam III to be recognized with BeamGage software?

Note; this answer applies to new Pyrocam III's that are shipped with BeamGage software or have been upgraded to work with BeamGage software. If a Pyrocam III is not licensed to work with BeamGage software, then the license needs to purchased and the Pyrocam III will need to be upgraded first. 

The Pyrocam III uses the 1394a 400MBS protocol, but will operate as a 1394b 800MBS interface card, however it will revert still to the 1394a 400MBS protocol. 

The Pyrocam III with BeamGage also uses a separately installed device driver which may not install and operate correctly at first. 

Note for Windows 7. Windows 7 contains a new set of 1394 OHCI Compliant Host Controller drivers that will not communicate with the Pyrocam III. When the Pyrocam III is plugged into a Windows 7 computer nothing happens. No indication can be found that the Pyrocam III is plugged into the computer. The problem lies with the new OHCI Compliant Host Controller driver. 

The solution is to replace the default "Texas Instruments 1394 OHCI Compliant Host Controller" with the "1394 OHCI Compliant Host Controller (Legacy)". 

To replace the default Texas Instruments 1394 OHCI Compliant Host Controller:

  • Open up Control Panel. Switch the View by in the upper right corner to Large Icons. Click on Device Manager.
  • Click the arrow next to "IEEE 1394 Bus host controllers".
  • Right-click on the 1394 port you wish to "fix", select Update Driver…
  • The Hardware Update Wizard is displayed. Select "Browse my computer for driver software" .
  • Select "Let me pick from a list of device drivers on my computer".
  • Select "1394 OHCI Compliant Host Controller (Legacy)". Click the Next> button.
  • When the Microsoft driver is installed, click the Close button.

The Pyrocam III Camera Driver Installation version 1.0 is available from our web address; 

We recommend that you right mouse click on the Setup.exe and "Run as Administrator". 

If the Pyrocam III Camera Driver Installation version 1.0 doesn't work to install the Pyrocam3Wdf.sys driver properly, you may have to do the following; 

Go to the Device Manager and with the Pyrocam III connected you should see it (probably) listed under Imaging Devices with a yellow exclamation error mark. Right click on it and select Update Driver Software… 

Do not install automatically. Do install from a list. Do not search, but do install from a specific location. 

Select Browse my computer for driver software and then select Browse to C:\Program Files\Spiricon\PyrocamKMDF\ and it will install the correct driver from there. 


When or is the Pyrocam III going to get higher resolution?

The Pyrocam™ IIIHR & Pyrocam IV series with higher resolution are now available. For more information please access the webpage at the link below;


Illegal System DLL Relocation error with Windows Update and Pyrocam III

There is a Microsoft Windows XP update (KB925902) that causes an Illegal System DLL Relocation error with the Pyrocam III Control Console. Microsoft has released a hot fix for the problem with the RealTek Audio, and the fix also works for The Pyrocam III Control Console.

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...

How to Profile Large, Small, and High Power Laser Beams

Don’t you wish there was a one size fits all beam profiler? I know I do. The problem is that the very thing that makes a beam profiler so perfect for one laser renders it useless for a different laser. At the risk of overcomplicating matters, we like to provide our customers with maximum flexibility. So you can indeed get one laser beam profiler and use it with many different kinds of laser beams – you’ll just need the proper accessories to use with each laser. There are two main issues that will come up: laser intensity and beam size. (Wavelength is of course important too, but that has more Read more...
