Hello, I am an active participant since 3 months now.
I am building a set-up to reduce my beam size from 3mm to 1 micron. I used a large combinations of lenses but always had issues in size. So i decided to use a 1 micron pinhole. I want to ask for an expertise to know if it works.
Should i converge the beam a little and then put the pinhole?
Thanks in advance
