We have studied the optical quality of holographic notch filters and have identified that stray illumination during the exposure stage and substrate scatter are the limiting factors. We propose and analyze a novel holographic recording scheme in which the substrate is rotated during exposure. Using this method, we have produced high-uniformity, flare-free dichromated gelatin notch filters with optical density greater than 5 and with scatter comparable with that from polished substrates.
