I've been seeing this back view mirror which is additionally used in cars in order to widen the back view, so one can see what's going on at the back of one's car..
It looks suspiciously like a fresnel , complete with the grooves and concentric rings while the other side is flat.
Is it usable as a fresnel in a projector? or do i need to resort to buying proper ones(costs a bomb where im staying!)
Thanks
