Help with lens - Click HERE for Original Thread

Hi,

Due to physical constraints on my design, it is almost impossible for me to have the LCD upside down, so I was wondering if anybody knew of any projections lenses that would let me work without inverting the picture.

The lens should be about the same size of a slide projector's one. And I guess the less fl the better. Thanks in advance.

Unfortunately, there's no such thing (almost true - there are specialised prism assemblies available at high prices).
Why not turn your whole projector upside-down - you might need to re-organise the lamp mounting and cooling, but it shouldn't be too hard.
You could always invert the screen instead:D

Hi,
The first one is the right sort of thing, but i suspect it's much too small for the purpose. I think you'd have trouble getting it in the right position (optically) anyway - at least as difficult as redesigning your projector layout. However, at that price why not experiment!
