lens for 808 nm

[Arayan]

In your experience, what kind of lens is better to use to focalize an 808 nm laser beam?

:thanks:

PS: I'm sorry if it's already been said but I tried to search in threads but I haven't found anything about it.

Usually 808nm comes at high powers, so you'd want a glass lens. To do it really neat you can take two cylindrical lenses, but a good ar coated (for 808nm of course) glass lens would also do fine.

I have been looking on and off at the same thing....these are a couple links that have been helpful to me at least.
The first is to lab modules that you can get on ebay for $100 and have the corrective optics inside. One person sells the parts too...
