Divergent Light Sensors

There are three ways to measure divergent LED, laser and other sources: First, is the integrating sphere, which is designed to capture all the light that enters it. Next, is to simply use a very large aperture, and place it close enough to the light source to contain most or all of the power. Finally, measure power or energy density. In this case, it is not necessary for all the laser light to hit the sensor.
