Line Laser Profiling & Analysis

DataRay's specialized beam profiler systems are unique solutions inspired by our customers' needs and applications. The first such system we developed, the Line Laser Profiling System (LLPS) is an excellent solution for direct measurement and analysis of line lasers up to 500 mm in length and down to 55 µm in thickness.

The LLPS's line laser profiling functionality is powered by our full-featured, user-centric software. The DataRay software automatically moves our flagship WinCamD-LCM beam profiling camera across the length of the line laser output using a 50, 200, or 500 mm translation stage to capture and analyze the entire beam. The DataRay software compensates for any residual sensor tilt to ensure an accurate measurement.

A full image of the line laser intensity distribution is generated, along with a vertical centroid plot, line width plot, intensity plots, and several other useful metrics. The software enables the user to generate annotated PDF reports, as well as export the raw data.

Figure 1: Line laser with edges physically blocked to reduce it to 28 mm in length. The diffraction seen near the edges is due to the physical blocking of the line laser; this can be observed with the DataRay software (Figure 3).

Figure 3: The characteristic pattern of edge diffraction from our physically truncated line laser in Figure 1 can be viewed in the Normalized Summed Intensity plot in red (second plot is zoomed). The red line is the summed intensity of each column and the green line is the peak intensity of each column.
Figure 4: The plots on top show the Y centroids without Residual Sensor Tilt Compensation for an extreme case with a sensor with <0.5 degrees tilt. The plots on the bottom show the Y centroids with Residual Sensor Tilt Compensation. Many cameras will not have any noticeable tilt effect, but the option is there if needed.
