To calculate a pinhole diameter fill in the below information.

SBIR recommends using a pinhole NO SMALLER than 3 times your sensor's IFOV and NO LARGER than 50 times your sensor's IFOV

If you do not know the IFOV for your sensor then please click this link IFOV Calculator for a calculator that allows you to determine the IFOV given specific sensor input parameters.
