Abstract

Microoptics is a generic term for miniaturized refractive, reflective, diffractive or hybrid components with characteristic dimensions in submillimeter range but larger than the wavelength. For their fabrication, subtractive, modifying or additive technologies can be used. Compared to macrooptics, scale-variant properties have to be taken into account for the system design. Arrays of microlenses enable a multichannel processing of light and are of particular interest for many applications like collimation, focusing, imaging, guiding or coupling of light from lasers, light emitting diodes (LED), waveguides, fibers, or other sources. The progress in nanooptics, microstructured fibers, or adaptive optical devices will lead to more complex optical systems with microoptical building blocks as an essential part within.
