Hi all, I bought a 1mw red laser off Amazon.co.uk for a few quid (mainly to play with the cat/dog), and was wondering if I could confirm it really is 1mw as I've heard a few horror stories here and there
I don't want accuracy. Even if the estimate is 100% or even 200% off, that would still be some kind of reassurance.
One idea is to aim at the lips, because obviously they're quite heat sensitive. When I tried to do that, I don't feel any kind of heat sensation on my lips from the laser whatsoever. Does that mean it must be 1mw or at least below 5mw?
Another idea is to shut my eyelids, and point at them, and see how that compares to directly overhead sunlight on a cloudless day (again shutting my eyes). One tends to see a bright orange like this - perhaps a 1mw red laser would appear as bright as the sun in this case?
Any other 'quick and dirty' methods of approximating the power (or perhaps even more usefully), the lux? Here's the laser btw: http://www.amazon.co.uk/gp/product/B009DRXDTG/ref=oh_details_o01_s00_i00
