    Was the fresnel lense on the sensor you took apart mounted flat, or was it
bent in a curve?    The fresnel lenses I got from Amperex are supposed to be
flat, but I'm wondering if I'd be able to get better coverage with a bit of
bending.   They're not your usually fresnel lenses, though.  Each element is
made up of several concentric circle-lenses (I'm sure there's a term for
this).
