WebLight emitting diodes (LED) have output intensities that are specified in two types of units: radiant intensity (mW/sr = milliWatts per steradian) and luminous intensity (photometric units) (mcd = millicandelas = millilumens per steradian = mlm/sr) at a typical forward current (e.g. 20 mA) and at the peak of the forward emission radiation pattern. WebFeb 1, 2016 · The reverse of which is that the minimum safe viewing distance for your IRLED would be (0.4W/sr)/ (100W/m^2) = d^2 = 0.004 -> sqrt (0.004)= 0.063246m. So yes your math for min safe distance was correct. But again I'd just like to point out that your laser tag system doesn't take 1000 seconds to send the pulsed light.
