1 3.1.2 Laser Beam Analysis Systems BeamStar Greatest ease of use Automated operation Effortless report generation Start/stop measurement Background subtraction for improved accuracy measurements Beam Wander screen Cross hairs for vertical and horizontal profiles. Profile can be linked to cross hair position, centroid, peak or sum profile can be displayed 3D display can be rotated or angled at will. Mouse button-shift moves image, mouse button-alt sizes image. A wealth of display choices are available in the menu When laser power is entered, the vertical profile graph is shown in meaningful units of W/cm2 Profile graph shows profile chosen in the 2D display. Flexible system allows user to open as many profile screens as desired and choose X and/or Y profile or sum profile for each. Shown is the Gaussian fit screen. A top hat fit screen can also be shown Origin is centered on CCD center location for ease of use Add button to add additional screens. This flexible system allows user to customize screen Description of Other Control Pages and Functions Setup for photodiode triggering with no need for connection to laser Pre trigger allows automatic synchronization with even subnanosecond laser pulses Automated or manual shutter, gain and background control All numerical values are shown in this compact screen. Note close agreement between 3 different measures of beam width in this unretouched measurement of a HeNe laser. Tailor digital camera format to needs in terms of effective pixel area, dynamic range and pixel density. This allows optimum use of resolution and speed For pulsed lasers, setup for external electrical trigger or exclusive photodiode self triggering Choose to display line or sum profiles With line profiles choose from 3 different reference points or numerical control User can click on this and enter laser power. BeamStar will subsequently follow power correctly Choose whether profile will be x, y or both and whether to align to xy axis or profile axis For latest updates please visit our website:

2 Top Hat Function Choose which results you wish to display Pass / Fail Choose X or Y profile Available for all functions with numerical results. Click on pass/fail and open dialog box Pass / Fail: values selected in dialog box will show green if pass and red if fail Top Hat: Choose boundaries for analysis Major/Minor Axes Alignment and Other Features Measure the distance from any point to any other point by right clicking on the mouse at the first point, moving to second point then right clicking again. Mark the position of the peak and centroid on the 2D display Display can be set to align automatically with major/minor axes of image as well as XY. Region of Interest A region of interest can be selected and then all calculations and pictures will refer only to the selected area. Note how in the picture on the left, the beam width values are meaningless because of the two separate beams while on the right, with region of interest, we get good readings for the beam selected. The region of interest can also be used to reduce background noise from surrounding areas for small beam and increase measurement accuracy. For latest updates please visit our website:

3 Beam Wander Screen This sophisticated and easy to use beam wander function allows you to track and record laser beam movement with time. Choose time limit for measurement Summary of data shown each period in log file Concurrent with screen, log data to file in csv or text format Record data in microns or input distance from source and measure in microradians For latest updates please visit our website:
