Commercialization of Microlenses

In the previous chapters, we discussed the importance of microlenses in communications, imaging, lithography, displays, and sensors. Although microlenses have undergone rapid development in recent years, most studies of microlenses, especially tunable types, are still preliminary, and their market applications remain limited. The most common applications are solid microlens arrays, as discussed in Chapter 4. Microlenses with different characteristics such as size, focal length, and fill factor are commercially available. 

Currently, certain issues limit the commercialization of microlenses. Addressing these issues will shape the future development of these devices.
