I posted this article originally on my web site because it gives such a good explanation of the complete process for making lenses. The article by Walter E. Burton was published in the Aug. 1939 issue of Popular Photography.
I made the copy using my digital camera as it is contained in a bound copy of the issues from July of that year. There is some distortion as a result due to curvature of the pages.
The photos that accompanied the story are at the bottom of the article; click on them to display at full size.
