Panavision 3D
Panavision 3D is a system developed by Panavision for presenting 3-D film in a digital cinema. It is a passive stereoscopic 3D system that utilizes spectral comb filters produced using thin-film optics technology. The visible spectrum is broken into alternate bands of light that evenly span the entire visible spectrum.
In June 2012 the Panavision 3D system was discontinued by DVPO Theatrical, who marketed it on behalf of Panavision, citing "challenging global economic and 3D market conditions".[1]
