  • Great explanation. ...

    Great explanation. I didn't realize there was a difference in the smooth/rough sides of a fresnel lens. I'll be experimenting with that.

    You would make a good science teacher, and I wouldn't be bored at all. I'm a professional photographer and you've taught me more about Focal Length than I ever understood in photography class, honestly.

  • This brings back ...

    This brings back memories of Physics labs, where we found the focal length by using the reflection method. This way is far much cooler. Write a book Dan please do.
