Heliac is a company located in Hørsholm, Denmark. They produce polymer foil solar concentrators for medium size utility installations. They have developed a process to create a clear film with a profile that mimics the shape of traditional fresnel lens for a fraction of the cost. When mounted on a frame the solar cooker fresnel lens has an aperture area of 105cm x 140cm. The focal point has been purposely broadened, giving a spot size of 8cm in diameter. The focal length is 200cm, this being the distance the refracted rays travel before reaching the bottom of the pot.
