Figure 4

Ray-trace and comparison of optical performance. (a,b) Manufacturer black-box lens model and spot diagram for 0, 7.5, and 10.5 degree object space field angles. (c,d) Empirically measured prescription schematic, ray-trace, and spot diagram. Transverse ray aberration plots showing ray error over normalized pupil coordinates of (e) model vs (f) measured prescription at the design wavelengths.
