Hi All,
New Blender user here. Bare with me. 
I have a lens created in Freecad, imported into Blender. I’ve been attempting to model the refractive index and transparency of PMAA (approx 1.485 and 0.93 respectively).
I sort of managed to set these to lens, moved the camera into place and tried a few light types to mimic the red LED which sites just behind it. When doing so I get some refraction but the center pieces are opaque. Thinking this was to do with being able only to see reflections I stuck a panel in front and moved the camera to view that, but now there’s nothing to see.
I’ve attached the .blend file, could anyone with a moment to spare sort it out? I can then study the settings and see what was done. Ultimately I have two aims,
-
to ensure the light is going out horizontally with little vertical refraction and to view spread (all via the front plane)
-
to ensure light isn’t reflected backwards (reduced efficiency). I’m unsure how easy this is with Blender, but perhaps a second plane behind it?
Many thanks - it’s quite important I turn the gestimate lens into something with a reasonable chance of success as the plastic mould costs aren’t cheap!
Thanks,
Andrew, UK
