What is the line pair per mm resolution of Boson lenses at MTF=50%?

This is not the typical method used by FLIR to specify lens performance. We typically specify MTF at a particular resolution (e.g., 50% Nyquist). For f/1 lenses and 12 micron pixels, the combination of theoretical diffraction and detector MTF results in 50% MTF at approximately 30 lp/mm. Accounting for non-theoretical blur, 50% system MTF is typically closer to 26 lp/mm for most Boson lens configurations.
