Default Re: WTB 6x cylindrical lens set

I got my lenses as well! Thanks again Glutton for the GB!
I don't have an immediate use for them, so I should have plenty of time to figure out some sort of mounting setup. In the meantime, keep up these per posed mounting ideas. They are really helping me to think of a starting point!

Glad to hear they arrived. Hope to see how you end up mounting them and how they work out for you.

Default Re: WTB 6x cylindrical lens set

I have my lenses too, received awhile back, but haven't used them yet. I have the electronics background, but machining, nope! Nothing here to do that, but I did play around with them awhile and for now, I think I will stick with the regular 2 inch expansion I am using with my NUBM44, the divergence is low enough, the output a ribbon instead of a spot, but with the amount of divergence I have, it doesn't really matter that much. I will use these for a build which doesn't have that amount of expansion.

Yea, for cutting, you don't want a fat beam! I'm tempted to PBS cube two of these NUBM44's

Hello. Have you heard anything more about the cylindrical lenses yet?
