Modeling of Microlens Array with Different Lens Shapes
Microlens arrays are useful in many applications, such as imaging, wavefront sensing, light homogenizing, and so on. Due to different fabrication techniques and for different purposes, the microlenses can appear in different shapes. In this example, microlens array with different lens shapes – square and round – are modeled. That leads to apertures in different shapes, and the difference in the focal plane due to aperture effects is shown clearly. The change of the focal spots with respect to the imposed aberration in the input field is demonstrated.
