Fresnel Lens Features
Glass-silicon materials Fresnel condenser lens and solar panels generally use the box design approach that we can achieve the best results. Solar arrays used Fresnel condenser lens, precision optical components is due to long-term exposure to outdoor air in the work environment, so use this product for the ultra-white toughened glass substrates, molding silicone gel inside attached Fresnel Seoul lens, precision thin thread forming process, and ensured high refractive index, optical losses to the minimum, and to high-intensity, high transmittance and anti-aging, anti - ultraviolet radiation, resistance characteristics of the climate for solar cells several times greater than normal capacity. According to the condenser customers than size and solar panels designed Fresnel lens on the edge of the Fresnel lens size and solar panels to the distance to focus achieve the best results and to be installed in a Japan tracker of photovoltaic power generation systems.
