Hello, 

I looked at the Mirror-5C in Auto-CAD-3D, and I've generated all the 3D-points for the edges (See picture attached) to take the measurements and calculating the average thickness of the four sides; as you can see on the attached table. 
The mirror thickness average was 25.08[mm] with a SE of 0.81. Besides I calculated the radio sphere for this coordinates and it gave me a value of 2751.06[mm].
