Hello
I decided to buy a cheap green laser pointer,for fun,and for pointing to stars.
I've bought one last year,from internet ( this type ),it cost 15$.It was advertised with 500mW,on the box was written <5mW, and on another side <1mW.On the sticker near the cap,was <500mW written.I haven't got a measurement tool,so I can't tell the right power.I can find on sites like ebay,amazon,or okazii(in my country) this kind of laser with power from 5mW - 1000mW. Are they all the same power actually ? Which are there real power ?
Anyway the laser has been dropped more times,and the dot went bigger and blurrier.I tried to disassemble it, but I failed epicly. Anyway I could rotate a piece,and the distance between the diode and a small magnifier went greater or smaller, the dot(outputted thing) likewise.
So I want to buy a new one,maybe the same type.But I found a new type,with plastic button,at nearly the same price,advertised with 500 mw , this one . If you scroll down, you can see a picture with the cap and the plastic button,but I cannot understand how it's turned on,if the button is not pressed.I asked the seller, and he told me that its power is the same as this one .
Has anybody this kind of laser ? What is it's real power ?
Thanks in advance.
Have a nice day
