Optical micro lens is a type of lens that has a micrometer diameter that is divided into two types: spherical microlens as well as aspherical microlens. It can be used in the fields of electron microscopy, photolithography virtual and augmented realities, as well as medicine. In addition, aspherical Microlens is a lens that has more intricate shape, that can be used to correct the light’s deviation and enhance the quality of imaging.

In optics the term “convex lens” refers to an optical lens made of glass with the capacity to focus on light rays which are directed straight into the direction of the opposite side. Microlenses can also be one of the lenses, however its diameter is at the micrometer-level. Because both convex and microlenses lenses are able to focus light rays and are categorized as convex lenses.

In a nutshell, a microlens is a convex lens that has the size of a micrometer and numerous applications. Microlens lenses are an intriguing optical device for people who are knowledgeable about optics, nanotechnology and microtechnology.
