The Shafer´s lens

In this blog I present my own designs, such as mobile phone cameras, microscope lenses, photographic lenses...

I also solve exercises of books like "Introduction to Lens" the Joseph Geary, I teach to calculate some systems and I leave links of interest. 

As David Shafer, an ongoing source of inspiration as the title of this blog attests, once wrote, “lens design is all about using pure thought, with some computer assistance, to bring new design forms into existence”. If you happen to think like that, this is your site.
