DepthQ Polarization Modulator
DepthQ Polarization Modulator

DepthQ Passive Polarization for Advanced 3D Visualization. Newly patented* technology makes DepthQ the world’s fastest polarization switch for advanced 3D visualization. With a powered, symmetrical 50 microsecond switching time between the eyes, DepthQ easily ensures bright, low-crosstalk operation - even at the upcoming 3D HFR (high frame rate) targets of 192 FPS, 240 FPS...and beyond. When combined with a silver screen, the DepthQ Polarization Modulator allows your 3D-ready projector to display stunning stereoscopic 3D content, viewable using inexpensive passive circular polarized glasses. Paired with projectors up to 30K Lumens, DepthQ provides a spectacular 3D experience for screens up to 17.7m (58ft). The new DepthQ Polarization Modulators electronically switch the polarization orientation of light passing through them. In combination with a polarization-preserving screen and a single-lens stereoscopic 3D projector (as bright as you need - no lamp/Lumens limit with the large modulator), this enables high-brightness, low-ghost viewing using lightweight & comfortable passive 3D eyewear.
