Anyone ever have custom work done making a lens in China? Probably a specialty lens manufacturer would be needed for something like this, making the possibilities fewer and the price far higher.
Right. But look at the divergence the spec sheet gives for a 30um emitter. Its like 1.6 X 7mRad. That's gonna need some more help.It is the collimator ^^^^
I think there is MM diodes for that spec's. It didn't say it's for NUBM44
The FL of these is over an inch. You would need something with a bit shorter FL.What about one of these is a large aixiz type module and large barrel?? I’d totally make one if I had a lathe...

A plastic lens might melt when used with high powered lasers.What about one of these is a large aixiz type module and large barrel?? I’d totally make one if I had a lathe...
