Solar Energy Fresnel Lens FSS**0 Specification Size: **0mm***0mm Focal Length:**2mm Thickness: **3mm Material: Acrylic Solar Concentrator /Collector New applications have appeared in solar energy utilization, where Fresnel lenses are used to concentrate sunlight (with a ratio of almost **0:1) onto solar cells. Thus the active solar cell surface can be reduced to a fraction compared to conventional solar modules. This offers a considerable cost-saving potential by low material consumption, and it is possible to use high-quality and expensive solar cells, which achieve a very high efficiency under concentration due to thermodynamic effects. Fresnel reflectors are also currently being incorporated into next-generation solar thermal energy systems TPV (thermal photovoltaic system). Characteristics of Fresnel lens made by Fscreen Energy concentration ratio ****5%; Optical PMMA with excellent light transmittance of *0%; Optimum lens design fit your application; Size ranged from *0 ****0 mm in diameter; Dimensions : usually it&#**9;s circle, we could make square-shaped by cutting Effective Diameter : The area of fresnel pattern without border Effective Focal Length EFL : the distance from the fresnel lens to the focused point Center Thickness CT : The thickness of lense without consideration for height of peak of lens Focal Length Tolerance :5% Dimensional Tolerance : 0.1mm Thickness Tolerance :*0% Transmission : *2% (from *******0nm) Index of Refraction nd: 1.*9 Material: Optical PMMA Operating Temperature (centigrade): *0 (Maximum) Applications: Solar energy concentration Photovoltaic CPV (Concentration Photovoltaic) CPT (Concentration Photothermic) TPV (Thermal Photovoltaic) Customization: Can make up to dia. 2m You can order: Fresnel lens design, trial-manufacture and mass production.
