Abstract (en)
[origin: EP1258846A2] A segmented Fresnel lens with a spherical surface is described, comprising a plurality of Fresnel lens segments able to concentrate the respective detection rays onto an optical sensor (10) disposed in the focal region (11) of the lens, the lens (1) having two bands one above the other (5, 6) on the outside, each with nine plastic segments (S), whilst said Fresnel lens segments or radiation segments are (17) in number, thus distributed from bottom to top on four bands one above the other: three segments in the bottom band (C), five segments in the middle band (B), six segments in the middle band (A) and three segments in the top band (D). <IMAGE>
