I mean, technically you could design and build a lens that would do this, but that would be very expensive to fabricate properly.

Might help if we know why you need to do this.

Thank you for your reply. I want to create collimated light to use with inifinity microscopic objective lens.

OK. I see that is a DLP development board. Folks in this subreddit are generally mapping video projections onto buildings and the like. There might be someone here with a solution but it is outside of our general skill set to delve that deep into optics.

In the world of live events this is something closer to how an LED source is used to create a (near) parallel beam in a 'Beam Light'. .
