Hi folks, I changed my page a little. The address is: http://www.geocities.com/Paris/Rue/4414/zp/zpenglish.htm I'm not sure if everything is working properly, I hope it is. If you care to take a look I'll be pleased. If something doesn't work, please let me know and I'll try to fix it. I am including some pinhole too, not only zone plates.
Cheers Joao
