One way Harkness addresses the 3D market is with screen surfaces that are available for both 'passive' and 'active' 3D projection for film or digital, using either single- or dual-projector solutions. Rear projection surfaces for 3D applications are also available.
In order to provide the best possible image, screen seams need to remain inconspicuous to viewers. To create uniform reflectivity throughout its visible surface, all seams on Harkness' 3D screens are virtually invisible under projection conditions.
"The screen surface is one of the least costly items when outfitting a cinema, but it can have a major impact on the viewing experience," says Andrew Robinson, managing director of Harkness Screens. "As 3D technology continues to expand and become more prevalent in cinemas and at special events, the need for a high-quality screen surface increases as well. Harkness takes pride in being able to offer premium 3D solutions no matter the application or type of technology being used."
The Spectral 240, commonly referred to as a "silver screen", is used for 'passive' front projection with 3D systems using polarized light. The extinction ratio is high and provides spectacular 3D images. The surface also supports 2D images and can be used successfully in applications where 2D and 3D are both shown. The intrinsically high gain (2.4) overcomes light losses in 3D systems.
Harkness' Perlux surfaces are recommended for 'active' (shutter eyewear) 3D systems and 'passive' systems not using polarized light. Three levels of gain (1.4, 1.8 and 2.2) are available from different screen sizes to overcome inherent light losses in 3D projection. All Perlux screens provide excellent images with 2D projection as well. Perlux gain screens reduce lamp power requirements, which can save on operating costs.
The RP 3D screen is specially formulated for 'passive' 3D systems using polarized light in applications where rear projection is required.
Harkness' Matt Plus screens are considered by leading cinema exhibitors worldwide to be the best matt white projection surface. The flexible PVC-based material is manufactured to a unique formulation and specification providing wide viewing angles, high contrast, bright pictures and excellent color temperature.
