I’m trying to make a high power beam dump in the form of a triangle with a slit for the incident power.
The idea is that each surface should be X% absorptive and that the beam should bounce around between the three multiple times before enough of it’s energy dissipates.
I’m getting constant errors with either not enough segments, or geometry errors.
Also, I’m wondering if there might be a better way to “coat” it with a X% absorptive coat.
What I’ve been doing, is placing a very thin piece of glass in front of each detector and coating the glass accordingly.
