Array Surfaces / Elements
Optical elements can be arranged in a regular grid, i.e. they are repeated
many times at specified X/Y locations with respect to the local coordinate of
Examples of array elements are (see also Figure above),
a) fresnel lens array,
b) spherical lens array,
c) GRIN rod array,
d) triangular surface array.
Array properties can be combined with any type of surface, i.e. spherical,
aspheric, Fresnel, GRIN and so on.
Wavefront plot of lens array with spherical surfaces. The array extension is
defined by size and shape of the aperture of the base (channel) surface.
