Hey I’m wondering if anyone has any input about using the 1.9mm fish eye lens on a Fire-I camera. I have the 2.1mm lens now and it does not capture the whole screen of the table that I’m in the process of building. The table is speced to have a FTIR 24"x32" screen.

By using a fish eye do you lose tracking capability? Also is this a valid screen size for a FTIR table.

You will need to add more calibration points to compensate for the extreme distortion, but it should work.

Does anyone have an equation that will derive the sight area
of a lens.
