    Default Focus

    Hello,

    I moved a little more into my laser hobby and bought a few more chinese lasers to compliment my first one

    What i've noticed with the one of them, is the green is no where near as a sharp as the others - all the same units, CNI lasers (apparently)

    Can these things be focussed? I see adjustment on the red and blue, but the green not so much. If not, what else might cause this. All optics seem clean.

    I have read recently that some of the green diodes are defective and dim quickly. If its a reputable company, they shouldn't have a problem replacing it. Make a video and send it to them. Unfortunately you'll probably have to cover the return postage. Thats what happened to me.
