Earlier Fresnel Lenses,Refraction occurs when a ray passes through surfaces separating materials with different indices of refraction. The contour of these surfaces define the focusing properties of the optical element. The bulk of material between the refracting surfaces has little effect on the optics of the lens.

Solar Thermal Concentrator Systems,Nonimaging Fresnel lenses can only concentrate the direct fraction of solar radiation. Solar resource assessments are necessary to evaluate the suitability of locations for the installation of solar concentrating collectors and to estimate their potential for energy conversion.
