Abstract
A method is described for absorbing radiant energy by means of a pair of radiant energy sinks maintained at different temperatures. A dispersive element separates the incident energy into two wavelength bands. Each band is absorbed by a heat sink that is black for that band, and has low emissivity in the wavelength range of the other band so that it does not radiate. The major portion of the heat load is removed by the high-temperature sink, while the apparent temperature of the system is nearly equivalent to the low-temperature sink. The conventional system, by contrast, removes all the radiant energy by means of a single heat sink at a temperature sufficiently low to cool the lowest energy source.
