A lens based on the concentration of electro-magnetic radiation through combined reflective and refractive properties of the lens. In one form of the lenticulated lens, radiation impinges and is transmitted through a substantially planar frontal surface. The incident radiation subsequent to being transmitted through the frontal surface impinges on a rear inclined surface forming a portion of the lenticulated rear surface of the lens. The ray is reflected from the mirror coated inclined surface and is egressed from the frontal surface and is refracted to a focus line. The incident rays impinging on the frontal surface are thus directed to the linear focus line when the lenticulations of the lens are linearly directed. By providing refraction and reflection passage of the incident rays from and through the lens, the reflected portion of the incident ray which is focused to a line focus is maximized.

A radiation concentrating lens for concentrating incident radiation to a positive focus, comprising: (a) a substantially planar frontal surface being at least partially radiation transmissive for passage of said incident radiation therethrough; and, (b) at least two substantially planar inclined rear surfaces of said lens, each of said rear surfaces having non-parallel envelope contours with respect to said frontal surface, said non-parallel envelope contours being inclined each with respect to the other for concentrating said incident radiation to said positive focus, said incident radiation passing through said frontal surface being substantially devoid of refraction prior to reflection on said inclined rear surfaces.
