Projector optics #23
Description
I'm playing with the optics for the projector. If I use a single tube lens, I can get a nice image focused on my sample, but it's hard to optimize for brightness, field of view, etc with a single lens. I think if the projector is to be as bright as possible, a lens needs to be placed as close as possible to it to collect as much light as possible, and at minimum a second lens to focus the image. Is this something you've experimented with? Do you have a sample design using multiple lenses?
