DepthQ Polarization Modulator   Lightspeeds™ DepthQ™ Polarization Modulator for active 3-D Stereo projectors supporting 120 Hz   Components The new DepthQ® Polarization Modulator electronically switches the polarization orientation of light passing through it. In combination with a polarization-preserving screen and a single-lens stereoscopic 3D projector like the ®DepthQ HD 3D Projector, this enables high-brightness, low-ghost viewing using lightweight & comfortable passive 3D eyewear. The DepthQ® Polarization Modulator utilizes a unique combination of separate liquid crystal elements bonded together, enabling both high polarization efficiency over visible wavelengths from 400 to 750 nm (predominantly achromatic spectral response) as well as fast transition switching speeds (<0.5ms at room temperature) between polarization states at frequencies from 120Hz to 400Hz. By actively alternating between two orthagonal polarization orientations in sync with progressive ‘page-flip’ stereoscopic data, matching polarized eyewear can passively block or transmit light to the viewer's eyes at the appropriate moment. Efficient, high-speed switching between the eyes ensures bright, low-crosstalk, flicker-free operation. The system includes both the liquid-crystal modulator as well as its control unit. A standard sync output from your graphics card or projector is supplied to the control unit, which then conditions the signal to match the modulator’s required input. The modulator is available in two sizes: Small (pictured), for projectors with apertures <2.75 inches (69.85mm), and Large, for projectors with apertures <7.12 inches (180.85mm). The optical window is also very heat-tolerant and can operate at temperatures up to 75 degrees Celsius (elevated temperatures actually enhance switching speeds). The DepthQ® Polarization Modulator is available pre-configured for either linear or circular polarization. Features DEPTHQ® POLARIZATION MODULATOR ADVANTAGES Viewer Comfort Passive glasses are very lightweight Single-projector solution eliminates possibility of geometric asymmetry between eyes No vertical or horizontal parallax problems No bulb differences (intensity and color temperature over time) Ease of set-up Modulator placement is simple and forgiving - just set it in front of the projector No time-consuming alignment of superimposed images required Lower Cost/Maintenance No moving parts Less hardware than two projector solutions No high-power Infra-Red emitter necessary Passive eyewear is inexpensive Options for Viewing Choose between circular or linear polarization models Passive glasses are available in a variety of form factors - from paper to plastic to wire-frame Versatililty Enables a wide range of applications - from theme parks & commercial 3D theaters to scientifc & industrial visualization Flexible Pricing Pricing model reflects application and use     Specifications subject to change without notice.   Product specifications may change at any time without notice.
