Details Photographers imaging in monochromatic light, such as Hydrogen Alpha, using an electronic sensor frequently encounter a wavy pattern of light and dark lines superimposed over their images. These lines are called interference fringes, interference patterns, or Newton's Rings. In long focal ratio applications, the nearly parallel light can internally reflect inside the image sensor or camera, causing an addition or subtraction of the light waves, resulting in the observed pattern. The Interference Eliminator solves this problem by tilting the camera off normal while keeping the center of the image sensor stationary, so that focus, framing, and vignetting are not changed with the tilt. The tilt changes the angle of incidence and optical path lengths inside the image sensor, mitigating the interference.
