These files contain lens design data used in:
Craig Kolb, Don Mitchell, and Pat Hanrahan. A Realistic Camera Model for Computer Graphics. SIGGRAPH '95 Proceedings, ACM SIGGRAPH, pages 317-324, August 1995
The tables are adapted from:
Warren J. Smith and Genesee Optics Software, Inc. Modern Lens Design: A Resource Manual. McGraw Hill, 1992 ISBN 0-07-059178-4
which in turn references corresponding patents.
Each table consists of a row for each lens surface. The final row indicates the distance from the last element to the image plane when focused at infinity. Comment lines start with the '#' character.
Each row consists of a number of columns. Each lens, except where noted, is given as a 100mm EFL design; the linear proportions of the design can be scaled by F/100 to arrive at a lens with a focal length of F mm.
Linear measurements are given in mm. Surfaces are listed from "front" (nearest object space) to "back" (nearest image space).
The first column indicates the type of surface:
- s: spherical
- d: diaphragm
The second column gives the radius of curvature of the surface. This column is blank for diaphragm entries.
The third column gives the axial position of the surface relative to the previous surface. Note that this differs from from traditional tables, where "thickness" is used.
The fourth column gives the index of refraction at the d line (.5876 microns) of the material on the "far" side of the interface. This column is blank for diaphragm entries. I have not included the Abbe number or the like in these tables, as we do not model chromatic aberration in our system.
The fifth column gives the diameter of the clear aperture of the interface.
