This site sells a fresnel lens that is 15.75"x19.69" and has a focal length of 700mm, can this be used in conjuction with the 125mm triplet sold at diyprojectorcompany? If so, what would be the distances needed between optics and the wall?
Thanks for you help. I own a home built projector with a 17" lcd and 135mm triplet, but I do not claim to be an optics guru. If someone smarter than I can guide me that would be greatly appreciated.

why don't u pick 500-600 mm
Good link but how can u order it though.
I think 700mm is good. However, you have to move your lcd and pj lense abit farther from the fresnel -> a little bigger box .. 🙂
