A method for calibrating lens grippers prior to use of the grippers in a lens manufacturing line includes providing a remote gripper calibration tool having an assembly plate and a Z-directional position sensor; providing a master gripper having a length dimension terminating in a tip, the length dimension being predetermined to match a desired final extension length of a lens gripper; mounting the master gripper to the assembly plate; measuring the Z-directional position of the tip of the master gripper with the Z-directional position sensor; unmounting the master gripper from the assembly plate; mounting a lens gripper to be calibrated to the assembly plate, the lens gripper having a tip, and calibrating the lens gripper by adjusting the final extension length of the tip of the lens gripper to a predetermined position relative to the measured Z-directional position of the tip of the master gripper.

A curable liquid is provided to a mold having a rigid surface disposed opposite a deformable surface. The curable liquid contacts the rigid surface and the deformable surface. The deformable surface is shaped according to a surface profile by driving actuators configured to move the deformable surface. The curable liquid is cured while the deformable surface is shaped according to the surface profile.

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.

Techniques for generating electronics components that operate free of unwanted distortions such as edge diffraction and unwanted phase jumps are described. A modified production master or a modified working stamp can be implemented to generate an electronic or optical component having structures that are positioned within a desired distance from a planar surface. A production master or a working stamp is modified in dependence upon a comparison of an identified distance for each respective structure to the planar surface and a desired distance. The modified production master or the modified working stamp generates the electronic or optical component by positioning the structures in accordance with the desired distance. By positioning the structures in accordance with the desired distance, electronic components generated using the modified production master or the modified working stamp minimize distortions, such as a phase jump between the structures.

Production of a lens member includes: a step of positioning a lens member having a first surface, which is a convex optical surface, and a second surface, which is an optical surface facing the first surface, in a predetermined attitude; a step of recognizing surface shape data of the first surface using a dimensional measurement result of the first surface of the positioned lens member; and a step of irradiating the first surface of the lens member with laser light to perform laser processing on the first surface, and controlling an irradiation position of the laser light based on the surface shape data.

In a method for the manufacture of a transmissive optical system from a blank, material ablation is achieved on the blank with an ablative laser, and the pulse duration of the ablative laser is less than 1 ns, and preferably lies between 3 fs and 100 fs, or between 100 fs and 10 ps.

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.

The present disclosure relates to an orthokeratology lens which may comprise an inner surface facing a cornea of a human eye when the orthokeratology lens is worn and an outer surface opposite the inner surface the inner surface comprising a centrally located base are zone, wherein the base arc zone is configure for pressing and shaping an anterior surface of the cornea to have a shape that conforms to the base are zone, wherein the base arc zone comprises two or more regions at least two of the two or more regions having different radii of curvature. The present disclosure also relates to a method for making orthokeratology he lenses.

In an example method of forming an optical film for an eyepiece, a curable material is dispensed into a space between a first and a second mold surface. A position of the first mold surface relative to the second mold surface is measured using a plurality of sensors. Each sensor measures a respective relative distance along a respective measurement axis between a respective point on a planar portion of the first mold surface and a respective point on a planar portion of the second mold surface. The measurement axes are parallel to each other, and the points define corresponding triangles on the first and second mold surfaces, respectively. The position of the first mold surface is adjusted relative to the second mold surface based on the measured position, and the curable material is cured to form the optical film.

A method of manufacturing an optical component having micro-structures is described. The method detects a crystallization temperature within a crystallization temperature interval for fully filling the molding material into a mold cavity to rapidly produce the optical element having a micro-structure with a large area.
