10, 12 and 14 bit systems are useful with new, low noise digital cameras. These are especially useful for viewing and measuring low level beam structure.

10, 12 or 14 bits provide better signal-to-noise ratios. This is especially useful when there is significant low level structure in the wings of a laser beam. 8 bit cameras benefit when summing or averaging is required to bring the signal out of noise. 10, 12 or 14 bit digitizers divide the noise into finer increments for a better definition of the systems noise content thus offering a more accurate analysis of the performance of the laser under test.

The Spiricon BeamGage and LBA systems as well as the Ophir BeamStar beam profiling systems come with a camera included. Additional or replacement cameras are available as are software upgrades. It is no longer possible to use your own camera with these advanced laser beam analyzer systems.

No. The LBA-100A is no longer provided. A trade-in allowance is provided for users who wish to trade-in an LBA-100A towards an LBA, BeamStar, or BeamGage system.

The wavelength response depends primarily on the camera used, but also on the optics used for beam sampling.

  • CCD cameras can see 266nm to 1.3µm
  • Our Pyrocam III cameras can see 190nm to >1000µm
  • InGaAs cameras are available for the 900 - 1,700nm wavelength region.

The new BeamGage application permits users to add additional calculations and computed results. These results are displayed on the screen, logged, and printed just as the standard calculations that are included with the application. Pass/Fail criteria may also be constructed with theses user defined computations.

Data files from BeamGage are available in HDF5 format which is an open source format compatible with tools like MatLab. LBA data can be exported in a number of formats such as ASCII, so that the data can be loaded into other programs for additional processing.

An ActiveX server provides LBA data, results, and beam image to another Windows application. You can also tell the LBA to Start, Stop, Calibrate and load a configuration via ActiveX. The ActiveX server works locally or over a network. Examples are provided with LBA for LabView, Excel and Visual Basic.

Yes, our beam profiling and power/energy measurement systems, once installed in a computer becomes a LabView virtual instrument, and can be controlled by a remote computer, or via ActiveX.

An ActiveX server provides beam profile, laser power/energy data, computational results, and beam image. You can also tell the application to Start, Stop, Calibrate and load a configuration via ActiveX. The ActiveX server works locally or over a network. Examples are provided to quickly get you up and running.

First let us start by describing what a Laser Beam Profile is. Typically you want to find out the intensity distribution of your laser beam so that you can make adjustments to your setup or laser to give you the best beam possible delivered to your work piece or experiment. By doing this you will reduce downtime and scrap. There are several types of profiling equipment on the market. More can be learned from our whitepapers on this subject at www.ophiropt.com/photonics. Here are a few examples of power spatial distribution from lasers. 

 
Laser Beam Analysis 
Laser Beam Analysis systems usually are a complete system where a Sales engineer meets with the customer and evaluates the needs of the customer based on their application. The system will then consist of all attenuation, sensor technology, and software that are needed to meet the customer’s requirements. This could also be considered a complete package. The BeamCube pictured below is an example of a fully integrated Laser Beam Analysis system.  
This system will take Beam Profile measurements, Temporal (Pulse Shape) measurements and Power measurements all at the same time. Each of these measurements can have a large effect on the processes you are using a laser for. Some applications require that you have a precise energy density for making the process work. Welding is an example of such an application. If the energy density is to low then the weld will not hold up. If the energy density is to high then you will blow through your weld. Temporal measurement of pulse shape can also be important in maintaining a process as some new lasers allow you to change the pulse shape of a laser for various applications. Then beam profile is usually important in most instances depending on the tolerance of your application. 
You may ask yourself what power ranges can be measured with Laser Beam Analysis equipment. There are solutions to measure lasers from nanowatts to kilowatts, and pulse widths from femtosecond to continuous wave (CW). 
Focal-Spot-Analyzer A Focal-Spot-Analyzer is a specific system containing a sensor (Camera/Scanning Slit) device based upon the beam size to look at the location and spot size of a focused spot. Cameras are an excellent solution if you would like to measure beams larger than 50 microns. Scanning slit technology lends itself to measuring small spots down to 6 microns and also the location of the exact focused spot. 
 
Each of the above devices can be used for measuring focused spot. The camera based system requires attenuation and thus will give you excellent results for 2d/3d and measurement of beams, but if you want to measure the exact location of your focused spot the NanoScan is the preferred device. The NanoScan is the industry standard for locating the exact focused spot. The reason is that for most applications the NanoScan does not require attenuation, so the mechanical tolerances can be measured to a high degree. We offer both of these options since there are many different types of lasers out there that need to be measured at focus. With low pulse rate lasers the camera is the best solution as the scanning slit requires laser repetition rates in excess of 1khz.

No. However, all files from Spiricon's earlier beam analyzers, including the LBA-100A, can be imported into the LBA system and BeamGage will import archived LBA data.

Since BeamGage supports the open source format, HDF5, so it can also import HDF5 files from other applications.
