ABSTRACT:
An apparatus for separating solar radiation into a longer wavelength component and a shorter wavelength component includes a concentrator of solar radiation, the concentrator having a focal point F.sub.1, and a mirror for selectively reflecting either the longer or the shorter wavelength component of the solar radiation spectrum. The mirror is positioned in the light path of solar radiation from the concentrator, the mirror having a focal point F.sub.2. The mirror includes a spectrally selective filter to make the mirror transparent to the non-reflected component of the solar radiation spectrum, thereby to allow the non-reflected component to pass through the mirror to a first receiver located at the focal point F.sub.1, and the mirror is appropriately curved in order to selectively concentrate and direct the reflected longer or shorter wavelength component to a second receiver located at the focal point F.sub.2.
