I'm planning on building a very short throw 1080p capable projector.
im planning on using a 15.4" wuxga LCD and in order to get the throw distance i want I'll need to use a lens with a focal length of around 180mm
my question is... is this screen size possible with this fresnel and lens setup? will the image look OK? or will the corners be dark and have the "barrel" look? would using a reflector and a few condenser lenses help the barrel effect?
attached is a picture of the focal calculator i'm using and the values therein.... im not concrete on any of the numbers all i know is that i want around that size of screen (120" horizontal) at that throw distance (around 5 feet) with a 15.4" lcd
any and all feedback would be greatly appreceated!!
