Down Projector
What kind of lens that I have to put in front of a video projector to reduce the size of the image?
I want to be able to use my projector to project video onto a screen of A4. Is there any type of lens can I put in the beam to focus it down to a size small Instead of the big picture you currently receive? Ideally, the projector must be as close to the A4 screen as possible.
The best will be convex on one side, and flat on the side facing the projector. You are not going to need some kind of dramatic curvature well. I went with something very soft, then work from there. If you have not heard speaking of Edmund Scientific, which is an excellent place to achieve the objectives, and can be found on any size or curvature or the type of lens you can imagine. They a good website too. http://scientificsonline.com/Default.asp?bhcd2=1184819637 follow the link to the optics. Good luck Kevin I have my glasses back on my head the first time. http://www.glenbrook.k12.il.us/gbssci/phys/CLass/refrn/u14l5b.html check it out for some basic optics. straightened me out!
