17" LCD + 80mm 330mmFL Triplet
I dont understand what would be the problem with a 17" lcd with an 80mm triplet with 330mm focal length. People have said that its too small, but I dont understand why. FOV of the triplets are supposed to be 45*, so theoretically this set up should work.
The 433mm is the diagonal 17" of the lcd. As the diagram shows, it would have a maximum angle to the triplet of 33*. Yet everyone says the 80mm triplet is too small. Am I missing something?
Thanks

An externally hosted image should be here but it was not working when we last tested it.

Check DIY PC. I responded over there. The short answer is, the FOV for the setup you proposed is actually 66 degrees not 33. 33 is the half angle. So these lenses have a half angle of around 17 deg - 25 deg.
