Topic: Invisible mirror edges
Message: Posted by: joderijck (Mar 21, 2019 02:34PM)
I am working hard on making a mirror completely invisible for the moment. The hard part are the edges... It for an effect where the mirrors float in mid air, let say its work a million dollars :)
I heard there are inox mirrors where you don't have the thick visible edge but they reflect less well. Are there other ways to have mirrors without the visible glass edge?

You probably ought to be looking primarily at "first-surface" mirrors because the thick edge is primarily the result of secondary reflection. The most faithful first-surface mirrors are on a glass substrate but they can be pretty expensive and heavy, and all these materials get more expensive with thickness which may be necessary to counteract warping and the resultant distortion of the image. Other materials would be aluminized mylar film (applied over a flat, stiff backing), aluminized acrylic sheet or stainless steel (there may be others but these come to mind). All of these surfaces can exhibit their own "artifacts" and you'll probably have to experiment with your actual lighting to see what results you can get for what you want to spend. You also may need to bevel the edge away from the front if you're trying to avoid seeing the mechanical edge (to make it somewhat more angle-proof). Good luck.

I have had good luck with mirrors with beveled edges.
You may want to check that out.

I have seen flat black paint feathering the edges of a m in a m box. It blended into the fabric and totally blocked the edge blue of glass that could otherwise be seen.
