I have just acquired a pen as described in the title... anything more technical about its components and I don't know.
It has a focus ring on it and I was just wanting to know, when I twist the ring to focus (too much and it unscrews itself off), but when I twist to loosen it, it becomes slightly loose which slightly upsets the stableness of the laser beam unless I hold it in place, is this normal?
The LP looks just like this one: http://laserpointerforums.com/f51/s...embly-photo-tutorial-picture-heavy-58889.html except it doesn't have the spring coil or white tape around the focus ring... it just unscrews off... Actually, thinking about the purpose of that spring on the lens housing, I think that's why when I twist mine to focus, it's a bit loose, I imagine that spring keeps it in place steady, so could I get hold of one of this springs or is it a simple DIY thing?
Also how do I focus to infinity?
Thanks
