Abstract
The present invention relates to an apparatus which allows producing elements with individually patterned anisotropic properties, where the pattern may vary from element to element. An apparatus according to the invention comprises a support for a substrate and an exposure unit for providing spatially modulated aligning light with a first polarization plane, wherein the exposure unit contains a light source, a spatial light modulator, which can be controlled electronically, for example by a computer, and a projection lens. The present invention furthermore relates to a method for fast production of elements with individually patterned anisotropic properties using such an apparatus.

Apparatus for the production of elements with individually patterned anisotropic property, comprising
- a support for a substrate and
- an exposure unit for providing spatially intensity modulated aligning light with a first and with a second polarization plane, wherein the exposure unit contains
- a light source,
- a spatial light intensity modulator, which is controlled electronically, and which is a digital mirror device or an organic light emitting diode display,
- a polarizer, and
- a projection lens,
- wherein the polarizer is arranged between the spatial light intensity modulator and the designated position of the substrate on the support and wherein changing of the polarization plane is controlled electronically.
