Since I am not entirely sure what system you wish to model with micro optics but quite likely that you will need a mixed mode to model the micro lens array more efficient.. You may look up some of the mixed mode example and the NS objects to find out a bit more. 6i;q=N$'

If you are new to ZEMAX, it may be a bit confusing using mixed mode but it should be doable. All the best.
