RayJackONE - Fly’s Eye Condenser

A fly’s eye condenser consists of two lenslet arrays.

In the example below, we use identical lenslets with rectangular apertures on each side of a glass plate and illuminate with the nearly collimated light of an LED source. The lenslets are dimensioned such that they form a Koehler integrator, which produces a very homogenous rectangular intensity pattern in the far-field with the same aspect ratio as that of the lenslets’ apertures.

Due to the employed voxel-tracing algorithm, RayJack ONE® is very efficient in ray-tracing arrayed structures. The latter can be created conveniently using nested for-loops in Python.
