This anisotropicplus video describes what a Fresnel lens is, how they work, what the focal length means with a laser demonstration and a Lens holder made out of 1″ PVC pipe including a solar alignment device. Information on the negative impact of haze, clouds and poor solar alignment is also presented. Should the grooves face the sun or the target is also analyzed.
