I found this auction in my searches. Someone looking for a condensor lens might benefit from this auction.

What type of lens is this for?

Is this the type of lens that you would need if you want a relatively short distance between the ohp and the screen, but want a large image projected?

The only lens that I think may be of any use is the condensor lens. This is used to focus the light inside your OHP, common to most of the "better" OHP models. I would have tried this lens in my old ELMO OHP if I hadn't allready upgraded to a 3M9550. As far as I know it will have no affect on distance to screen.

ok,

but what can this lens be used for though?

 

[zardoz]

It could be used in the "refit" of an OHP projector...look to the OHP modification threads for further info on the use of a condensor lens. YWH has some excellant pictures of OHP's that use condensor lens's.
