Need help finding materials for a laser

I'm trying to build a blu-ray laser... Long story short, I need to find a lens and housing for it. What I would do is get the laser diode, put it into a housing, and then put the housing into a little tube. Inside the little tube, I'd insert a protoboard instead of a PCB. I would then insert the tube into an empty flashlight tube.

What I need is a lens and a housing for the diode. Any help finding these things would be appreciated.

It would be best if you searched before you posted this.. this is one of the most common of knowledge on here..but just to help, aixis...

Oo... sorry >_> thanks

yeah... suedolobster, or lasersbee will rip ya apart "figuratively speaking" for not searching first. AIXIZ HOUSING. 2 word answere.

oh, and since your "new" to housing diodes... buy the diode PRE pressed into the module... they dont just pop in. they get pressed in almost permanently... so be careful
