When to Use the D86 Beam Width Measurement Method

WebThe beam divergence defines how much the beam spreads out over increasing distance from the optical aperture. Beam divergence is defined by the full angle. ... Values stated are typically within +/-10%. The light … WebSep 15, 2016 · The D86 method of beam width measurement uses a power enclosure, rather than the profile of the beam to determine the beam width. To calculate the width of the beam with the D86 method, a circle (see Fig. 1a) or ellipse (see Fig. 1b) is first found which encloses 86.5% of the total power across the sensor. The D86 method is named … greater than value sql
