Physicists use a unit called a steradian to measure "solid" angles when they encounter problems in 3-dimensional geometry. Steradians are particularly important in astronomy and in optics, but they arise in any field where physicists need to study the flow of particles through a given area. You might notice that the term "steradian ...1 steradian has a surface area of 1m^2 at a range of 1m, 4m^2 at 2m, 100m^2 at 10m, 0.01m^2 at 0.1m, etc. So assuming there are no additional optics, the irradiance at distance D metres will be 3/D^2 W/m^2 for your 3W/sr source. To take a step back though, you get roughly 1.5kW/m^2 irradiance from the sun.১৯ জুল, ২০১৩ ... What is the conversion between degrees and steradians?
