An optical device is presented that uses the highly wavelength dispersive nature of diffractive optics to provide a means of either removing a small waveband of incident radiation from a scene, to function as a tunable notch filter, or passing only a small waveband of incident radiation from the scene, to function as a tunable bandpass filter. A prototype design example is presented along with preliminary performance analysis.
