The Daystar Interference Eliminator can be used between the camera and the Quark to adjust the light angle and extinct the interference pattern – or Newton’s Rings.

The effect is similar to interference testing of an optical surface between two flat surfaces. The sensor and cover slip cause a small interferometer inside the camera and cause a Newton’s Ring moire’ pattern. The CCD chip must be tilted to a minor degree to prevent this pattern. Recent advances in aftermarket adapters offer a simplified solution for the issue. This effect is a concern for both color and monochrome sensors.
