Disclosed is a lens assembly having a first cylindrical microlens having a first microlens longitudinal axis. A flat sheet of material having a hole therein is attached to the microlens, with the microlens traversing the hole. The microlens is oriented with the first microlens longitudinal axis being parallel to the flat sheet, such that the microlens can be illuminated through the hole. In a second embodiment, a second microlens is attached on the opposite side of the sheet and is oriented at an angle relative to the first microlens.
