Hi Ra
In you second-last post I assume you meant -
"You can clearly see that the glass based TIR at the LEFT side of the pic is much more transparent than the acrylic one at the right, "
Keep up the great work. I started building my first telesope in 1963, but I'm still learning much about torch optics from your posts.
I'm currently building a focusable SST50 headlamp and will start posting when I have some photos.
