Abstract
A color wheel comprised of two or more interference filters deposited on or bonded to a substrate 30 without the use of a frame or spokes. Filters 32, 34, and 36 preferably abut and are typically made from multiple layers of materials having different indices of refraction. The color wheel does not require extensive machining or balancing, and is very optically efficient because the duration of single color light periods is maximized. The color wheel does not have a frame or spokes and is therefore more aerodynamically efficient resulting in less work required to spin it and less wind noise.
