Summary
[edit]DescriptionOff-axis focusing.png |
English: Left: Collimation of light from two point sources into two directions, within the plane of incidence.[1] Right: Outside the plane of incidence, the light from two different points projects into two directions within an arc shape (dashed curve), as long as the mirror is curved to focus the light, e.g., onto projection optics or the object plane.[2] The arc presents a range of azimuthal illumination angles (for each point) in the plane of the illuminated object. |
