Full Scale Zoom to Center

: diffraction limited spot, for λ=42 nm

The scale is in units scaled to the distance of a physical evaluation plane. For example, if you are 1 furlong away from the optical system, the scale would be in furlongs.

Actual magnification is the magnification value given multiplied by the distance to the physical image. Paraxially, the value given is 1/(focal length), but negative if the image is inverted.

Actual magnification is the magnification value given divided by the distance to the physical object. Paraxially, the value given is the focal length, but negative if the image is inverted.

Magnification is the ratio of the slope of an output ray to the slope of an input ray.

This is a cartoon drawing made for clarity, rather than being to scale. So in many situations, the order of surfaces may be different than what is shown.

Note: Paraxial parameters do NOT take into account any aspheric components.

(1): Object position (this is an input parameter)
(2): Front focal plane
(3): Front principal plane
(4): Back principal plane
(5): Back focal plane
(6): Image plane (this is NOT the same as the evaluation surface)
(7): Distance from object to front principal plane
(8): Effective focal length
(9): Distance from back principal plane to image plane
(10): Entrance pupil position
(11): Entrance pupil radius
(12): Exit pupil position
(13): Exit pupil radius
