Worked for me....  I just don't know all the proper numbers to put in for a real zone plate.  But with guess work I got an image of a zone plate when I opened the file in Photoshop.

Subject: [pinhole-discussion] Zone Plate Image Generator

 Folks, I have created a zone plate image generator so that I could make my own zone plates. The program downloads a .BMP so it's PC centric, I think. The idea was to use the program to generate a zone plate image and then take it to the bureau to have it put to film. They charge about $15.00 for this. I haven't tried it out yet so I don't know how well it works. I'll be visiting them on Friday and I'll drop it off then. The calculator/generator is at http://www.MrPinhole.com/zp.html Larry@MrPinhole.com

It's a well-known fact that although the public is fine when taken individually, when it forms itself into large groups, it tends to act as though it has one partially consumed Pez tablet for a brain.
