The Revolutionary 4K Christie Solaria 6P Cinema Projector is What 3D Needs
SMPTE 196M recommends 16 foot-lamberts for commercial movie theaters but the usual lght level in 3D theatres is more often between 3 and 4 foot-lamberts. Now, the new "4K Solaria 6P" 6-primaries laser projector from Christie is providing enough light to put full brightness on screens up to 23 meters wide.
First Seeen in China in June
The first Christie permanent, pure-laser projection system installation was unveiled on June 13, 2014 at the Shanghai Film Art Center, the first Cineplex to be built in China. It dazzled audiences with 60,000 lumens of brightness and a contrast ratio of 3,000:1 on a 1.4 gain high uniformity white screen measuring 23 meters in width.
How it Works
“There are actually two reds, two greens and two blues coming out of the projector, each separated by a 20 nanometer guard ban,” explained Don Shaw, Ph.D. and senior director of product management of entertainment solutions at Christie Digital Systems in Cypress Calif. “Since this doesn’t involve filters or spinning wheels,” Shaw said, “this allows us to transmit the light with 90 percent efficiency.”
