The coating system (10) may have a second coating apparatus, such as a spin coating apparatus.

A method for producing a semi-finished spectacle lens and a semi-finished spectacle lens includes identifying the semi-finished spectacle lens by applying a removable sticker having a unique code to the semi-finished spectacle lens. The semi-finished spectacle lens has an embossed code that is engraved into the semi-finished spectacle lens. The sticker is applied to at least partially cover the embossed code. The sticker can be applied directly onto the semi-finished spectacle lens early in the manufacturing process, for example immediately after molding or injection molding. The sticker can also be applied to the semi-finished spectacle lens before further surface treatment is carried out.

Described are systems and techniques for characterizing optical fibers. Disclosed systems and techniques employ optical metrology, functional metrology, or both to characterize microstructured optical fibers and determine fiber characteristics, errors, and quality control metrics. The characteristics, errors, and quality control metrics are useful for improving the manufacturing of optical fibers.

A method of deriving an appropriate condition for cutting a polarizing plate, the method including: (a) preparing a polarizing plate including an adhesive layer and having a cut surface; (b) providing the polarizing plate so that one end of the polarizing plate adjoins a guide unit; (c) moving the polarizing plate on the guide unit; (d) measuring frictional force applied between the polarizing plate and the guide unit while moving the polarizing plate; and (e) deriving the appropriate condition for cutting the polarizing plate based on the measured value of the frictional force and a predetermined adhesive agent leakage determination criterion based on the frictional force.

On a first aspect, the spectacle lens is selected as including a transparent support in which is coded an identifier readable by an external reading tool for retrieving the identifier. A distant server is contacted using the identifier and data related to the spectacle lens is so gathered. On a second aspect, data related to the spectacle lens is provided to a predetermined database. Upon receiving a request issued from a requester, the database is accessed and at least some of the data is retrieved, the request including at least part of the identifier, and the retrieved data is sent to the requester.

An optical bonding machine is provided, including a transparent datum located within the optical bonding machine, wherein the transparent datum supports a first substrate, a robotic placement head configured to pick up a second substrate and place the second substrate into contact with the first substrate, on the transparent datum, a camera disposed proximate the transparent datum, the camera capturing a video of a flow of an optically clear adhesive between the first substrate and the second substrate, and a curing source disposed proximate the transparent datum, the curing source emitting UV rays that pass through the transparent datum and the first substrate to cure an optically clear adhesive between a bonded substrate comprising the first substrate, the optically clear adhesive, and the second substrate. An associated method is also provided.

This invention relates to a die tool, a device and a method for producing, in particular embossing, a monolithic lens wafer that has a large number of microlenses.

A real-time calculation system capable of computing the industrial optical performance and yields of a prescription laboratory is disclosed. The system uses statistical analysis to determine the compensation factors that can be applied to given products, Semi-Finish, materials, or lens designs to increase the lab yields. Using a monitoring and configuration system, the user tracks the evolution of the laboratory's performance and identifies areas in which yields are impacted. The user defines how the calculation system will optimize the laboratory's performance, such as by defining how the compensation factors will be calculated and applied.

An imprinting method, which includes following steps. A workpiece is conveyed to a working region by a first conveyer unit. The workpiece is imprinted in the working region through an imprinting segment of a flexible imprinting mold film. The flexible imprinting mold film is driven by a driving roller set, such that at least another one of the imprinting segments of the flexible imprinting mold film rolled around the driving roller set is expanded from the driving roller set and moved to the working region.
