Just to be clear, you inquired about both variable control which you had read about in one of my
posts, as well as the burning cap for the laser, and it not being a short focal point:
The Original 'burning cap' I made for these were only good for a few inches
as the focus was fixed, and there was no real way to stretch the focal point further away
from the aperture. The solution was an external beam expander...
You were quite specific in requests, they were not my suggestions, which brought me to come up with :
