Systems are described that disperse the wavelength bands corresponding to the channel centers at a faster rate than the bandwidth of the channels themselves. An embodiment consists of a double element system including a grating, to create the initial separation, and a segmented mirror with multiple flat facets of different tilt, which reflect each spatially separated channel at a different angle. The size, position and angle of the facets are designed to match the spacing and position of individual channels of known wavelength and number that are diffracting from a grating with a predefined period, a set distance from this device. This system enables the individual channels to be re-imaged at some later point with a large separation between the channels, relative to their spatial size.
