A method for polishing a workpiece in the production of an optical element, in particular for microlithography, wherein a relative movement takes place between a polishing tool (300) and a workpiece surface (110, 120, 210) being machined. A polishing tool surface (215, 315) of the polishing tool (300) is formed by a viscoelastic polishing medium (303), wherein the polishing tool surface has an average diameter which is less than 50% of the average diameter of the workpiece surface being machined. The polishing tool surface during polishing is guided by an overrun distance beyond at least one edge (110a, 110b, 120a, 120b, 210a, 210b) delimiting the workpiece surface being machined, wherein the average diameter of the polishing tool surface is at least twice the overrun distance.

A transportation carrier is provided for automated lens manufacturing in a lens manufacturing facility, including: at least one block piece or one block piece receiving section; and an electronic paper display configured to display at least an up-to-date status information of the manufacturing process of the optical elements carried by the transportation carrier that is intelligible for a human operator without use of a reading device, the electronic paper display including a wireless communication module and a memory configured to exchange and to memorize job information and to process information for lenses to be manufactured, in which the electronic paper display is further configured to function as a passive RFID tag with the wireless communication module.

Examples are directed to an approach to specifying design guidelines for fabricating a free-form optical component, and methods of fabricating the free-form optical components. In one example, a family of optical prescriptions is created, and a fabricator may manufacture the free-form optical element to any selected prescription within the family. According to certain examples, the series of prescriptions in the family each describe a very similar optical surface providing the same or similar optical performance, and are layered relative to one another such that the thickness of the optical element at any point is slightly less for each subsequent surface defined by the next prescription in the series.

A holder to polish a fiber optic connector having at least two ferrule assembly. Each ferrule assembly having a ferrule with an optical fiber therein. And a tool to rotate a ferrule assembly within the connector housing to allow opposing ferrules, with an APC surface, to transfer a light signal with minimal surface reflection, or data loss.

An optical machine (AV) for treatment and/or processing optical workpieces (L) has a machine frame (MG) on which a workpiece holding arrangement (WH) is movably supported and at least two treatment and/or processing devices (DB1, DB2, DB3) for treatment and/or processing a workpiece. The workpiece holding arrangement has a plurality of partition walls (TW) which separate and delimit at least three work spaces (AR1, AR2, AR3, AR4) from one another. The work spaces can be moved, together with the workpiece holding arrangement.

To each work space, a workpiece holder (CH) is assigned for the purpose of parallel use of the work spaces. Each work space can be moved, together with the workpiece holding arrangement, with respect to the machine frame in a movement cycle from a loading station (PS) on the machine frame, via stationary treatment and/or processing stations (DS, CS) which are spatially distanced from the loading station.
