Microelectronics and Micro-Electro-Mechanical Systems (MEMS) advantageously pervade our daily lives in a wide span of applications ranging from telecommunications to medical instrumentation, offering benefits represented by microcircuits and micromachined structures, which can be illustrated by computer processors, sensors (detectors) and actuators.

Optics has proven its great usefulness for centuries and serves at least as many fields as microelectronics and microsystems do. The breadth of the field keeps thousands of research groups busy with themes such as geometrical optics, photonics, optoelectronics, electro-optics, which have made spectacles, photodetection, lasers and fiber optics possible, just to name a few.

The combination of optical devices with the functionality posed by microelectronics and MEMS is often termed OPTRONICS. A typical example of an optronic device is an image sensor (digital camera - CCD/CMOS), which comprises photodetectors and electronic circuitry either on- or off-chip, besides optical filters, micro-lenses and objective lenses. Other interesting optronic systems involve adaptive optical components, as deformable mirrors and wavefront sensors, which also combine optical and electronic functionality in their operation. Usually, if there is micromachining involved in the fabrication of these devices, they are labeled Micro-Opto-Electro-Mechanical-System (MOEMS) devices.
