A microlens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometres (µm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to optical diffraction at the small features. A typical microlens may be a single element with one plane surface and one spherical convex ...

What is microlens? microlens is a lens library, just like lens, but smaller. It provides essential lenses and traversals (like _1 and _Just), as well as ones which are simply nice to have (like each, at, and ix), and some combinators (like failing and singular), but everything else is stripped. As the result, microlens has no dependencies.
