Thanks your remarks ,
For the blue-purple laser , because commonly human eyes has less sense on blue-purple than green light , so when same mW put together ( although we test with machine to show that they are exactly the same ) , people feel green is far more bright ,
More professional of this is , even same person , they might have different feeling on color , like red , green , blue , because different person eyes might has small different sense range .
So with my personal feeling , If you point blue-purple laser to Pure White or fluorescent material (attached one is 5mW star blue purple), 50mW green is similar to 200mW ,,,
But if on other material , maybe 50mW green is similar to more higher than 200mW blue-purple .
(One of my friend say 20mW Green is same as 200mW blue-purple too . For your reference only , pls consider clearly.)
Another thing has to remind is : Blue-purple laser has much dangerous than green , because if high power blue-purple point into eyes , people still "feel" it is small case .... ___Invisible light is much more dangerous than visible one ,, Red laser too___
So , please remember : DO NOT POINT ANY LASER TO ANYOTHER PERSON'S EYES
Thank you
