Increase Your Projected Image

[Deimok]

Has anybody combined a single lense form an OHP and attached it to a triplet or copy lense? I experimented with this setup and found that I increased my projected image at least 2 times without image degradatation.

I don't know if this idea is well known, but is sure makes a difference if you live in a small place and dont have enough room to project a large image. I would be stuck with a projected image size of around 40" to 50" (not too sure, didnt measure without ohp lense), but with OHP lense attachment, I'm gettting a projected image of 75"

It works! So if this is old news, forgive me and ignore this, but if not!

Have fun!

That's nice, though the majority of us are trying to get a smaller image so we can put the projector behind the couch.

but for people in dorm rooms and such, this is a almost a perfect setup

A Lumenlabs triplet will fill a standard wall height at 10 feet when using a 15" screen. Most dorm rooms I've seen don't have a completely empty 12-foot wall. And they had enough room for a 7 or 8 foot throw, especially if you bolted the projector to a loft.
