Abstract: Apparatus and methods are described including a corrective optical element having a thickness and/or a curvature that is different in different regions of the corrective optical element, such that the corrective optical element is configured, upon being adhered to any one of a plurality of differently-shaped optically-corrective single-vision lenses, to change a focal length of the optically-corrective single-vision lens differently in different regions of the optically-corrective single-vision lens. The corrective optical element is shapeable such that the corrective optical element can conform with a shape of any one of the plurality of differently-shaped optically-corrective single-vision lenses. Other applications are also described.

Abstract: Apparatus and methods are described including a progressive lens that is configured to provide a far-vision correction and a near-vision correction. The progressive lens includes a single-focus, far-vision corrective lens that is configured to provide only a portion of the far-vision correction, and a film coupled to the single-focus, far-vision corrective lens. The film defines a far-vision corrective portion that is configured to provide the remainder of the far-vision correction, a near-vision corrective portion that is configured to provide additive near-vision correction, and an intermediate portion in which the film transitions between the far-vision corrective portion and the near-vision corrective portion. Other applications are also described.

Abstract: Apparatus and methods are described including generating a multi-focal lens and/or a progressive lens by adhering a corrective optical film to an optically-corrective single-focal lens, such as to change a focal length of the single-focal lens differently in different regions of the single-focal lens. Other applications are also described.

Abstract: Apparatus and methods are described, including a corrective optical film for converting a corrective single-focal lens to a multi-focal lens and/or a progressive lens. A thickness and/or a curvature of the corrective optical film is different in different regions of the corrective optical film, such that the corrective optical film is configured, upon being adhered to the single-focal lens, to change a focal length of the single-focal lens differently in different regions of the single-focal lens. Other applications are also described.

Abstract: A vacuum deposition apparatus comprising an enclosure adapted to receive a substrate to be treated and placed under a vacuum; at least one injector that generates a molecular beam of vapor of an organic material the injector comprising a conduit located inside the enclosure and traversing an injection wall of the enclosure to form an outer nozzle adapted in such a manner as to be hermetically connected in a detachable manner to an organic material supply, wherein the supply is a bottle whose neck is adapted to be introduced into the nozzle; an outer heating apparatus located on both sides of an injection wall and surrounding the bottle; an inner heating apparatus surrounding the conduit; and a regulatable valve permitting regulation of conductance of the injector in the enclosure.

Abstract: Epitaxy equipment including an epitaxy chamber under vacuum containing a substrate support and at least one cell under vacuum for evaporation of epitaxy material closed by a diaphragm having at least one opening and communicating with the epitaxy chamber by a connecting flange, and a mobile plate positioned opposite the diaphragm such that the distance of the plate from an exterior surface of the diaphragm is variable and has a section corresponding to a section of the diaphragm and a molecular beam is formed at the level of a zone surrounding the plate.
