helklo boys..... i tryed to use a binoculars with my 30mw green laser.. and i musyt say it makes a 1,3 cm beam diameter.. but very collimated.... at infinity!!
furst i focus the binoculasr at long distance,,, than i put the laser in ONE lense... and my other eye in the others........ wow.. i see a VERY LITTLE DOT that goes to infinity.. and rest supersmall at incredible distance... trust me... if not real 0mrad.... 0.1 for sure.
i am starting to think.....and what if a buy a monoculars at LOW PRICE at dealextreme? (they sell it) could work well?
surely for the mrad yes.... but... how about the lense?can block too light? i notice that it loose some power with binoculars... so i think that REAL beamexpander...ises special glass for 532nm.... but bey... if someone has power to sell with an over 100mw green laser... it is not a big problem to loose some power..... and everyone can do a beamExpander at low price
