A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.

An object of the present invention is to provide a curable composition that can be cured satisfactorily and can form a cured product having a high glass transition temperature as maintained and having high mechanical strength. A curable composition includes a siloxane (A), a cycloaliphatic epoxide (B), and a curing agent (C). The siloxane (A) contains at least two epoxy groups per molecule. The cycloaliphatic epoxide (B) in the curable composition is preferably a compound represented by Formula (I): ##STR00001##
wherein X is selected from a single bond and a linkage group.

A device for the laser-assisted processing of a material adhering to a substrate or a body that is associated with, or free of, a substrate or of its surface, in particular by TPA/MPA and/or by treatment with an ultrashort pulse laser. A sample holder of a positioning system holds the material to be processed. A laser source emits laser pulses or laser pulse sequences. Focusing optics shape the laser pulses or laser pulse sequences to impinge in a focal point or a focal volume in the region of the material or body to be processed so that a 2- or multi-photon polymerization can take place there, or in that they impinge in a focal point or in a focal volume in the region of the body in such a way that material located there or focal volume is subjected to the desired chemical and/or physical changes.

The invention relates to a method of manufacturing a microprojector for a projection display, wherein the microprojector comprises a support on which a projector lens array with a plurality of projector lenses is arranged, wherein on a side of the support facing away from the projector lens array, an object structure array with a plurality of e.g. identical object structures is arranged, wherein at least one projector lens is associated with one object structure such that the projections of the object structures superpose through the projector lenses to form a full image, wherein e.g. the distance between a projector lens and the associated object structures corresponds to the focal length of the respective projector lens, wherein on the object structure array, a condenser lens array is arranged such that in case of an illumination of the condenser lens array, a Köhler illumination of the object structures or projector lens associated with the respective condenser lenses is permitted.

Techniques related to optics formation using pick-up tools are disclosed. Optical elements are formed by pressing a pick-up tool (PUT) against elastomeric material deposited on a light-outputting side of light-emitting diode (LED) devices. Pressing the PUT against the elastomeric material causes a molded shape of the PUT to be transferred to the elastomeric material. This forms the optical elements in the elastomeric material.
