You need to brush up on your coordinates :-)
So do I as I use Moray to make my scenes
I've modified your scene for the mirror to be in the horizontal plane.
In real life you would not expect to see extinction over such short
distances so I've added unrealistic values. Truth be told I don't
think this is what you want.
I'm sure someone else will take over as I'm on the road shortly.
