This may not be a question regarding CIT, but I figured if anyone here at AVS will now about it, it would be here!
Simple question, is there a way of getting slightly bigger image using lenses in front of the projectors lens? If I'm not mistaking, I believe I've read something about fresnel lenses to make the image bigger, but I can't find that thread.
So the answer would be yes, with a fresnel lens! Right? Any specific ideas of how I would proceed from here? What kind of fresnel lens? Size? How do I mount? Potential problems?
Bump! Anyone? Aren't most fresnel lenses made out of poor quality plastic? I've searched the web a lot and I haven't found any examples of this, except people who mount fresnel lenses on their tv's. In theory it should work, but I haven't been able to prove it yet, seems like they are very hard to find. How big does it have to be? In my opinion, the bigger lens the less chromatic aberration.
Thanks for the tip! Though it was pretty expensive, did almost cost more than my PJ
There must be a way to make a DIY Navitar lens to put infront of the projectors lens. Should be possible to take a old photo lens appart and use one of the glass lenses inside, a wide angle lens should work. See if I can get my hands on one.
