THE WALKER LENSES
You need the book "Optical Engineering Fundamentals" by Bruce Walker to pursue these references. The Walker Lenses The Walker lenses are 11 designs that are described in the book "Optical Engineering Fundamentals, Second Edition", by Bruce H. Walker, McGraw-Hill 2009. They are included to simplify data entry for users who wish to experiment with the designs beyond the description given in the book. Some of the sign conventions, etc. differ from those used in OSLO. Nevertheless, the book is a good introduction to Optical Engineering, and is recommended particularly for new users. The lenses were all evaluated or designed using OSLO Light. There have been some changes in OSLO since these lenses were evaluated, principally concerning aplanatic ray aiming, default values for aperture divisions, and improved accuracy in a few algorithms. Consequently, you should expect to obtain slightly different results for some of the systems when you evaluate them on an OSLO Version 6 program. The lens are to be found in the directory publiclenlibwalkeropticaleng. The lens file names and page references in the book are as follows:
