Lens for NUBM31T

[Shiiru]

Hello,
Could anyone please advise me on what lens to choose for focusing a nubm31t array?

I had thought about using a meniscus lens or an F-Theta lens like Drake did but I have a lot of other things going on so I haven't ordered a nubm31 yet, been thinking about it though...........I would like to see a multi die 520nm like it or while were dreaming how about a grid of 10 x 10 BDR-209's for pumping a LEP

Hey can you tell me how you are driving it please I'm guessing regulate source to 20.5v and then split up into 4 lm338's set up for 3a and the 4 lm338's will be outputting 20.5v 3a?

Nah, I'm just using a power supply, although I don't think that matters when choosing a lens
