hi tescorp;
look at this time i looking for a paper Malleable for fit to the shell.
other important propiety is the reflectance , the most possible to a perfect mirror surface.
i will attach a pictures about this topic.
about de focal length ..
It is interesting to note You have two focal lengths to watch
1) focal distance between virtual focus in the ellipsoidal mirror .
in this for know distance focal distance divide (distance between focus) / 2 = and get distance focal in the system .
2) Another important topic is the distance between lcd vs focal plane of triplets.
Both factors are similar but can play with these . in order to get a better use of light.
tell me if not be clair pls.
tank you
