Fabback See-Thru Mirror
"See-Thru," or two-way mirror, is a semi-transparent film of
aluminum deposited on an acrylic or polycarbonate substrate, which
allows a percentage of incident light to pass through while
reflecting the remainder. From the illuminated side, it is a
mirror. From the darkened side, it becomes transparent. See-Thru
mirror has been used successfully in monitoring and surveillance
operations in such places as stores, correctional and psychiatric
institutions, hospitals and casinos. See-Thru mirror is also used
to make infinity lights and multiple images devices. It can be used
in advertising and for special theatrical props and effects.
