Laser Divergence Calculator Laser Divergence Calculator - divergence matters: Beam behavior over distance The beam divergence describes the widening of the beam over the distance. It is defined in milli-radiant (mrad), which usually describes a part of the circumcircle. Generally spoken, it is best to have a divergence as small as possible. The beam divergence is in direct relation to the beam size at aperture: By increasing the beam size at the aperture it is possible to reduce the divergence - and vice versa. This is possible to a certain extent, depending on the technology. To see the importance of the beam divergence, please make some example calculations with our divergence calculator - you can clearly see the importance if the distance is increased: Please fill in all values, at least for Laser 1 Distance [m]: Laser 1: Laser 2: Power [mW]: Power [mW]: Divergence [mrad]: Divergence [mrad]: Diameter at aperture [mm]: Diameter at aperture [mm]: Thousands separator: , Decimal separator: .
