In modern optics several demands exist for implementing microstructured optical components.
For example, diffractive optical elements (DOEs) are of considerable advantage in combination with refractive lenses to form so-called hybrid optical systems. The inverse chromatic dispersion of diffraction in contrast to refraction opens new possibilities for the compensation of chromatic aberrations.

Furthermore, the realization of a diffraction grating on a concave optical surface allows the functional integration of imaging and dispersing in one single optical component, which is a key enabler for miniaturization of spectroscopic systems. For more information about gratings, please see also Grating & Grism. In the sophisticated illumination systems microstructured beam shaping elements play an essential role.

Micro- and nanostructures in the subwavelength range open alternative solutions for antireflective properties and polarization management.
