Ok, today I received phr in aixiz module from HTD. I hooked it up on driver and battery. It is powerful and it burns but I just cant focus it. You know I want it focused as all normal 5mw lasers. When I focus it, let say to 10 m, and I point it at 20 meters the dot gets oval, big, and hard to be seen. I have 5mw green which is nothing special, but its dot is not that big at distance, its dot can be seen on about 200 m. I wonder if I can set my bluray to be focused like that?
