AF5D-60 is a sophisticated image stacking system. Airflex5D system uses the built-in grid system - QStack™ to easily & precisely stack multiple projectors into a bright, clear and vibrant image for 2D and 3D applications, without the hassles of additional software or camera., AF5D-60 can increase the brightness of any projected image by 2X (4X, 8X or even 16X). In comparison to the brightness of a single 12,000 lumens projector, the AF5D-60 can easily achieve this brightness by combining 4 (3000 lumens) projectors at a fraction of the cost. With the ease of alignment, Airflex5D create a 30,000 lumen projection system by using 10 projectors with 3,000 lumens and 5 AF5D-60. AF5D-60 works with your existing HD projectors, you can add brightness at anytime with the convenient setup of AF5D-60. Your entire high lumen projection system remains operational even if one projector bulb burns out. AF5D-60 is also capable of geometric correction to accommodate a curved screen or other large venue projections. Also, with soft edge blending, multiple projector systems can create an even bigger image. Pixel-based overlapping ensures precise alignment of the overlapping edges.
