Advanced Modeling of Microlens Arrays with VirtualLab Fusion

2021 22 November

In modern optical systems, the applications of microlens arrays (MLAs) cover a broad and varied range: as the main component in Shack-Hartmann sensors or in light field cameras, as collimating elements for emitter arrays (VCSEL or diode bars) or playing a vital role in diffusers and homogenizers. These are just some of the many uses to which this type of element can be put. The new Microlens Array component in the fast physical optics modeling and design software VirtualLab Fusion with its optional lateral channel decomposition technology makes the simulation of optical systems containing MLAs much more efficient and user-friendly. It gives control to the user, allowing him to investigate the behavior of each microlens in the array independently, or of all of them together. At the same time, all the perks of the field tracing technology that has become the signature of this powerful software are still there: the different modeling levels are the key to the consideration of diffraction in different parts of the system.
