Need Good Optics for a Blue Laser

I just built my first laser. It's just a blue laser in an aixiz lens. It's driven by an adjustible powers source, so I can adjust the power output to as high as I want. I typically run it around the 1W mark. The laser is powerful, beam is visible and it burns through cd jewel case as expected, however the default axiz optics bleed a lot of the light away. When the laser is shown on a wall, there is a very strong center dot, with a large halo. A fair amount of light is being bled into this halo. I did buy a glass collimating lens from stontek, but that module doesn't focus the beam as well as the default aixiz lens. Can anybody recommend a store and some optics for a blue laser in an aixiz module?
Feel free to post pictures of your results. If anybody is interested, I can post a picture.

You can get an AR coated lens from jayrob in his thread

I just recently bought one from here, will see how it works...

Hope this is what you're looking for
It could also help if you give more information about your build.
Good luck

I have a couple of Jayrob's 405-G1 lenses. They let through more light than the glass aixiz lenses do. I like mine real well but they aren't cheap and I need to get more from him.
