It is quite common for optical designers to compare different optical systems. When doing so, they often use MTF or modulation transfer function when doing so. It is usually used for those single lenses that is spherically shaped which are usually considered simple types to even the more complex types such as the telecentric imaging assembly which happens to be multi-element in nature.

Getting the right testing procedures is very necessary when it comes to undergoing this testing process.
