Glass or plastic.
For what power? (in mW)
What size?
The ones at the bottom of this page are 5mm x 5mm or 10mm x 10mm and very high quality. You have to ask CNI what the cost is for either of those. I have no idea.
I can sell you a single 5mm x 5mm glass one shipped anywhere in the world for $20. :bday:
