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 a surface. 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.
