Best power exists when the distance between the Fresnel lenses and the CPC equal to the focal length, unlike when the focal length is less than the distance (Partain & Fraas 318). The phenomenon occurs because of loss in the concentrated beam that falls on the CPC. Besides, focal point forms at CPC if focal length is longer than the distance. Therefore, change in the path of the incident beam results into loss of the beam (Fraden 164). First law of refraction highlights the if the distance between the Fresnel lenses and the CPC equal to the focal length, most of the beam will concentrated at exit aperture (Lindenfeld and Brahmia 241)
Moreover, the experiment established acceptance angle. Adjusting the Angle of incidence beam on the Fresnel lens (Tilt About x), when the distance between the Fresnel lenses and the CPC equal to the focal length as showing below.
Based on the experiment, we identified that power generated by the CPV system decrease with increase in the Incidence angle (Luque 89). Whereas, at a point where power equal to zero, the Incidence angle becomes the Acceptance angle, usually (4o). Hence, the system limits deviation of radiation falling more than three degrees (Fischer 140). As shown in Table ...Show more

6.9). Correspondingly, the material (PMMA), radial height (0.846 mm), and thickens (4mm) are added to the Fresnel 1 row (Illuminating Engineering Society 104), (Fig…

Imaging with the help of Magnetic Resonance Imaging, Computerized Tomography, Positron Emission Tomography and similar ones-has become very much popular and is in wide spread use-even in developing countries. The evolution of these techniques has been the outcome of the various drawbacks associated with older techniques like Nasal Radium Irradiation and others-which have had their effects-often irreversible, on the people on which they were used.
