I've been using the relative laser brightness calculator to figure out how beams at different wavelengths compare, but I've started to have some doubts about its accuracy. It says that 100-200mw of 650-660nm red should equal 5mw of 532nm green (for me, the red is much dimmer), and that a 50mw 405nm beam should be 7-10x less visible then the same red laser as before (for me, the violet is at least as visible as the red). I've looked through the forums to try and better data, but I've had little luck in finding hard numbers. So, in light of all that, I decided to come here and directly ask members about their personal experiences, and hopefully get enough data to create slightly better model.
The question: Given the exact same viewing conditions (background lighting, air quality, viewing angle, etc), how many mw of one wavelength does it take to match (X)mw of another? This question is specifically about the beam, not the dot.
Small details about the testing conditions and the beam diameters may be useful, but they are not required.
The ideal comparison would be in a dark room with clean air against a 532nm laser with a known power output, but that is also not required. Any wavelength can be compared to any other.
