A system is disclosed for measuring the transmission of light through a pair of eyeglasses having least one eyeglass lens mounted in a spectacle frame having a position of wear. The system comprises a light source, a support for mounting the eyeglasses, and a light detector coupled to the support. The support is configured to mount the eyeglasses with the position of wear relative to the light detector. A microprocessor is coupled to the light detector, and a display coupled to the processor. The processor receives spectral data from the light detector and outputs the spectral data to the display as a spectral curve.

A blocked lens assembly suitable for on-block processing and cleaning includes a blocked lens and a sealing member disposed on at least a portion of an edge and/or surface defined by the blocked lens. The blocked lens further includes a lens blank having a front surface and a back surface, a lens blocking piece to hold the lens blank while processing the back surface of the lens blank, and an adhesive layer, disposed between the front surface of the lens blank and the lens blocking piece, to affix the lens blank to the lens blocking piece. The sealing member protects the blocked lens so as to facilitate cleaning of the blocked lens while the lens blocking piece is affixed to the front surface of the lens blank

A module housing case is described. The modular housing case includes a fiber optic component housing defined as a cavity that is sized to receive a fiber optic connector. Within the cavity is a ferrule guide. The module housing case also has an internal cavity that is at least partially enclosed. Components to assist in magnification may be disposed at least partially within the internal cavity. Finally, the module housing case employs a camera lens alignment feature.

An apparatus and a method for optical measurement of an internal contour of a spectacle frame are disclosed. The apparatus contains an optical unit, which is configured to capture light reflected from an illuminated section of the inner contour of the spectacle frame. The optical unit is insertable into the inner contour of the spectacle frame and, when inserted as intended, is rotatable relative to the spectacle frame. The optical unit contains at least one light source, an objective, and at least one optical sensor, wherein the light source is configured to generate a light section, wherein at least one section of the inner contour is illuminable by the light section, wherein the objective is configured to image the illuminated section of the inner contour onto the optical sensor, and wherein the optical sensor is configured to capture the light reflected by the illuminated section of the inner contour.

The invention relates to a coolable optical table with a table top and at least three table legs. Securing means for securing objects such as optical elements are provided in a table surface of the table top. The table legs are equipped with a damping device for damping vibrations.

The purpose of this invention is to create a low cost, easy to use, fiber end face and or connector inspection tool component that easily adapts and converts most all mobile communication devices with camera, screen and software capabilities into a microscope. The invention encapsulates and holds firm a fiber connector body and or fiber connector bodies and or ferrule housing or ferrule housings for the purpose of viewing the cleanliness and quality of the fiber end face and or faces. A Fiber end face is the component area and or areas the embodies the fiber core and or fiber cores, fiber ferrule end and or ferrule ends and fiber related end component and or components that are instrumental in the mating with other like components with fiber connector plug end faces and or related optical fiber components for the purpose connectors and splices prior to connecting and or join optical fibers where a connect/disconnect capability is required.

A hybrid optical-electrical automated testing equipment (ATE) system can implement an optical test assembly that includes an electrical interface and an optical interface with an optical-electrical device under test. The optical assembly can include a socket on which the device is placed by the ATE system to connect electrical and optical connections. The optical connections can couple light through the socket and the optical assembly to one or more testing devices to perform efficient testing of optical devices, such as high-speed optical transceivers.

A test pattern (170) comprising a set of dots (174) which define a first ellipse (176) of best fit in which the major and minor axes R1, R2 are equal (i.e. a circle) is displayed on a plane surface and a digital image of the (usually distorted) test pattern seen through a lens is captured. A second ellipse of best fit joining the dots in the set is derived from the distorted test pattern in the image. Characteristics of the first and second ellipses are compared to determine the degree and nature of distortion to the test pattern, from which the power of the lens is calculated. The major and minor axes of the first and second ellipses may be compared. The test pattern can include a number of said sets of dots distributed over an area of the surface with each set being analysed to determine the optical parameters of the lens at multiple locations.

A container for a contact lens, having a micro-textured pattern on an interior surface thereof to prevent adherence of the lens to the container. In-container inspection of the lens within the container does not recognize the micro-textured pattern of the container as a defect on the lens.

A lens focusing device includes a lens holding module for clamping at least one test lens to be tested, a replaceable chart display module, and a focal length shortening module. The replaceable chart display module includes a frame structure, a first chart display element detachably disposed on the frame structure, and a plurality of second chart display elements detachably disposed on the frame structure, and each second chart display element is inclined at a predetermined angle relative to the first chart display element. The focal length shortening module includes a first focal length shortening structure and a plurality of second focal length shortening structures. The first focal length shortening structure is disposed between the at least one test lens and the first chart display element, and each second focal length shortening structure is disposed between the at least one test lens and the corresponding second chart display element.
