First thanks for any help on this topic. I figured somebody on here would be able to answer my questions with the knowledgeable members. I need a small green laser with beam size around 1/2 inch at 100yds. The laser beam needs to be centered with pointer. IE if I put laser pointer in lathe cut it on it does not draw a 2” circle 20 ft away on wall. I have bought about 5 different lasers and non of them are aligned with pointer, all of them shoot laser at angle from lense. Is this not possible with the way lasers are produced. If it is possible where would I look to purchad. Thanks for any help.
