Diffraction grating to compensate the dispersion.

摘要

A GRILLE IS USED TO REDUCE TRANSMISSION Chromatic Aberration in an optical system, by which the SYSTEM Chromatic dispersion is counteracted and substantially eliminated by induced dispersion diffraction GRILLE. GRILLE comprises a configuration Fresnel Facet MOLDEADAS Microscopic DIRECTLY IN ONE OF THE SYSTEM refracting optical surfaces. TYPICALLY FACETS would have a profile height APPROXIMATELY 0.00004 INCH AND A WIDTH PROFILE AT LEAST 0.003 inch. IN YOUR primary application, the invention improve performance FRESNEL LENSES OPTICAL CONCENTRATING SOLAR LIGHT USED FOR DIRECT IN A DAYTIME LIGHTING SYSTEM PIPING. For this application, it may reduce Chromatic Dispersion A TEN PERCENT WITH POOR PERFORMANCE OPTICS only 2%.
