Then we can run WebThe impact of surface irregularity on Strehl ratio is also dependent on the f/# of the lens. As a general rule, faster aspheres, or aspheres with smaller f/#’s, have greater sensitivity to surface irregularity’s impact on Strehl ratio. For example, Figure 4 compares an f/2 lens to an f/0.75 lens (both with 25mm diameter), and more Strehl ...
