BeamGage^® is a state-of-the-art beam profiling system that performs extensive data acquisition and analysis of laser beam parameters, such as beam size, shape, uniformity, divergence, mode content, and expected power distribution. The newest version features a major upgrade of the computation engine to improve cycle time, responsiveness of the user interface, and enhance the ability to work with apertures and partitions. This improves the performance and speed of the software, especially when analyzing different beams or sources of light (e.g. LEDs, optic fibers, etc.), and for heavy computations, such as measuring multiple beam profiles, comparing key statistics, and 3D viewing in real-time. BeamGage also features a new strip chart function that allows for zooming and panning, charting of partitions, and storing 10,000+ data points with no decrease in performance.

Measurement cycle time is critical in most beam profiling applications as knowing what the beam is doing dynamically has a drastic effect on the process outcome, especially in those first few seconds. Most laser processes start immediately, once power is turned on. Many process problems are traced back to dramatic spatial power changes within the first few seconds.

BeamGage includes more than 55 measurements and calculations, many based on ISO standards. These include fast, off-axis correction of distorted beam images; trend charting; data logging; power/energy calibration; and pass/fail production testing. Laser manufacturers and researchers can easily import their own custom algorithms created in C#/.NET using Custom Computations. This expands the software’s functionality to an even wider array of applications, from fiber optic signal analysis to production parts inspection to military targeting systems.
