Method of making lightweight, single crystal mirror

Номер: US20130052468A1
Автор: Vincent T. Bly

A method of making a mirror from a single crystal blank may include fine grinding top and bottom surfaces of the blank to be parallel. The blank may then be heat treated to near its melting temperature. An optical surface may be created on an optical side of the blank. A protector may be bonded to the optical surface. With the protector in place, the blank may be light weighted by grinding a non-optical surface of the blank using computer controlled grinding. The light weighting may include creating a structure having a substantially minimum mass necessary to maintain distortion of the mirror within a preset limit. A damaged layer of the non-optical surface caused by light weighting may be removed with an isotropic etch and/or repaired by heat treatment. If an oxide layer is present, the entire blank may then be etched using, for example, hydrofluoric acid. A reflecting coating may be deposited on the optical surface.

Silicone hydrogel materials with chemically bound wetting agents

Номер: US20130172504A1
Принадлежит: NOVARTIS AG

The invention provide a new class of silicone-containing prepolymers containing ethylenically unsaturated groups and latent UV-activated free radical generating moieties. This class of silicone-containing prepolymer is capable of being actinically crosslinked in the presence of one or more hydrophilic vinylic monomers to form a silicone hydrogel material with a hydrophilic surface without post curing surface treatment. The present invention is also related to silicone hydrogel contact lenses made from this class of silicone-containing prepolymers and a vinylic monomer having a latent UV-activated free radical generating moiety.
