When to Use the D86 Beam Width Measurement Method
Beam Profiling Concepts |September 15, 2016
Although the clip level method and the second moment method are the most popular methods of beam width measurement, other beam width measurement techniques such as the D86 method can be used with beam profiling cameras.
Scanning Slits vs. Cameras
Beam Profiling Concepts |August 4, 2016
Our customers often ask us what type of beam profiler they should use to measure their laser beam(s). In this blog post, we explain the relative advantages and disadvantages of a scanning slit profiler and a camera-based profiler.
Why We Tilt Our Filters
Beam Profiling Cameras |July 21, 2016
In this blog post, we explain why tilting our filters is necessary for an accurate beam measurement.
Setting the Right Capture Block
Beam Profiling Concepts |June 20, 2016
Centering the laser beam and properly sizing the capture block are important steps in taking accurate laser beam measurements with DataRay software. In this blog post we explain why the beam needs to be centered on the capture block, and the errors that can occur if the corners of the capture block are illuminated by the beam.
Systematic Error in ISO 11146 Measurements
Beam Profiling Concepts |May 12, 2016
Systematic error is an important calculation in any measurement system, and especially in ISO 11146 laser beam profiling measurements. In this blog post, we address the systematic error inherent to the measurement of beam width as laid out in the ISO 11146 standard.
Small Beam Width Theoretical and Experimental Error
Beam Profiling Concepts |March 14, 2016
One of the most important measurements in laser beam profiling is the beam width measurement. A common question we see is “How small of a beam can I measure with this camera?”
