The Ring-Array Concentrator (RAC) is
an ultra-powerful optical lens based on an array of nested ring reflectors.
This patented design is completely free from the light-dispersion effects
of conventional refractive lenses which allows for obtaining much higher
efficiencies and concentrations for a broad range of electromagnetic
energy spectrum. RAC forms a high-power beam on its rear side which can
be ideal for many solar
solar applications including high-concentration PV modules, electric
generators based on Stirling heat engines, high-heat furnaces, hydrogen
production, material processing, etc.
