Default Using a photo lens for collimating the beam

I was tired of my G2 lens which have a too wide beam at few meters away and decided to use my photo lens in front of the raw beam.
Divergence is far better and I have a 3mm beam at 4-5meters instead of a 30mm when properly focused.

I can burn easily any material including white very reflective ones, including tin solder at 4-5m.




Looking for a way to attach it correctly now , any advice welcome
