Hi, im Rich, otherwise known as coopdogg,
ive been craving a blue laser for some time now after my dad brought me a decent green laser back from thailand to use as a starpointer when im out with my telescope on the rare clear days we get.
well ive just been on my holidays to thailand and ive picked up the following blue laser.
as you can see in the first picture it quotes "20,000,mW" and a 450nm wavelength and states its class IVb
now the 20k mW i took with a pinch of salt, but i admit, the thing is powerful enough to burn your hand/set things on fire.
anyways, enough rabbiting on, im guessing the "engrish" translation should have been more like 2000mW
anyone have any experience with these cheap lasers?
