I've been spending some time on the diyprojectorcompany website, and while they don't have as much information/people as this site does, their information is a little mroe concentrated and newbie friendly.
Anyhoo, after digging around today I started wondering why we, as a community, could not design a long focal length triplet lens. I found a piece of free optical design software called OSLO-EDU, and it has a triplet lens in its library of example lenses. Could an experienced OSLO user tweak this lens to fit the needs of us that want to have larger projectors (15"+) at the back of our rooms (15-20 feet)? I searched the diyprojectorcompany website for OSLO references, and found only one, by Rox, who I believe also posts here.
After we had someone experienced design a triplet lens, wouldn't building one be as simple as buying three lenses of the appropiate spec off the shelf and placing them in a proper enclosure?
Am I mistaken in assuming that there would be a large demand for a triplet lens that would allow projectors to be placed at the back of the room instead of in the middle of a room?
I know that there must be challenges in such a project, or it probably would have already been done... I'd be willing to help in anyway I could though in getting something like this moving.
