    3.1. Standard Fresnel Lens versus Achromatic Design. As a first step the study of the incident light falling onto secondary’s entry surface is analyzed, taking into account the efficiency, flux uniformity, and thrown area. The employed lens will be a circular Fresnel or achromatic lens of which focal length is 155 mm and the radio size is mm.

    A manufacturable achromatic fresnel lens for CPV Abstract: The CPV industry has moved to very high concentration ratios (1000X or more) but the commonly used Fresnel lenses are limited to concentration ratios closer to 200X by chromatic aberration, leading manufacturers to turn to secondary optical elements, which increase cost and complexity.

  • Designing an achromatic doublet lens — OFH

    One of the most common optical structures is the achromatic doublet. They are used to reduce chromatic aberrations. At it’s most basic, it is is a two lens system configuration where one lens is a concave lens, usually made of a flint glass, and convex element, usually made with crown glass.
