Figure 5
Ray spot diagrams for an optical system with an image distance of = 150 cm (axis units: cm). Ray spot diagram (a) is obtained with the aberration coefficients dijk, hijk; (b) with dijk and , hijk and ; and (c) with ray-tracing program SHADOW. (I), (II) and (III) are for point sources with field angles of u1 = 0°, 0.1° and 0.2°, respectively. |
