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.

A method for manufacturing a spectacle lens according to at least one data set of edging data and a computer program product with instructions for performing the method are disclosed. A spectacle lens blank, semifinished spectacle lens product, or a finished spectacle lens product is inspected for defects and compared to a data set to determine if it can be manufactured into an edged finished spectacle lens that fits into a specific spectacle frame such that the defect is not present in the edged finished spectacle lens.

An inspection device for an optical ferrule includes one or more reflectors. Each reflector has a mating surface and a mirror disposed at an oblique angle with respect to the mating surface. Each reflector is configured to mate with the optical ferrule when the optical ferrule is disposed within a housing of an optical connector. When the mating surface of the reflector is in mated contact with the mating surface of the optical ferrule, the mirror is positioned to provide a reflected view of at least a portion of a mating surface of the optical ferrule.

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.

An extreme ultraviolet (EUV) collector inspection apparatus and method capable of precisely inspecting a contamination state of an EUV collector and EUV reflectance in accordance with the contamination state are provided. The EUV collector inspection apparatus includes a light source arranged in front of an EUV collector to be inspected and configured to output light in a visible light (VIS) band from UV rays, an optical device configured to output narrowband light from the light, and a camera configured to perform imaging from an UV band to a VIS band. An image by wavelength of the EUV collector is obtained by using the optical device and the camera and a contamination state of the EUV collector is inspected.

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 method for inspecting an ophthalmic lens for the presence of an unacceptable semi-opaque defect in a lens body thereof comprises the steps of: illuminating the lens body with laser light in an area bounded by an edge of the lens body; detecting the intensity of laser light scattered by the illuminated lens body in a predetermined detection direction which is different from a direction of reflection; comparing the detected intensity of the scattered laser light with a predetermined threshold intensity; determining a size of at least one coherent area in which the detected intensity of the scattered laser light is higher than the predetermined threshold intensity; determining whether the size of the at least one coherent area is larger than a predetermined threshold size, and rejecting the ophthalmic lens in case the size of the at least one coherent area is larger than the predetermined threshold size.

A manual inspection system and method to inspect for defects in Contact lenses comprising; an image acquisition system with at least two high resolution cameras; Top illumination light head used for acquiring Bright field images; a Backlit illumination module to acquire Dark field images; at least another back lit illumination module to acquire a different type of Bright field images; an interchangeable mechanism to change measurement gauges suitable for a particular product; a rotating wheel embedded with multiple optical filters to cater to different imaging requirements; a first camera to capture the full view of the contact lens at a beam splitter; a second camera suitably mounted on a swivel arm to capture a higher resolution image of a selected defective area as viewed on a projection screen; a glass template or measurement gauge mounted at a suitable position to achieve overlaid images of the lens and the gauge on a projection screen for taking measurements; a flexible template measurement gauge as an optional overlay, to replace the glass template, suitably mounted on the projection screen for easy measurement of defects and geometry of the contact lens; an XYZ table to position the contact lens; creating a database on the computer that tabulates geometrical information and detailed defect information along with their respective positional information; and subsequently analyzing the database images to arrive at corrective actions to the manufacturing process to improve the quality and yields in the contact lens.

The disclosure provides a system that may: provide multiple first portions of a laser beam to an objective lens of an optical system; provide the multiple first portions of the laser beam to respective multiple locations of a test surface; receive multiple second portions of the laser beam from the test surface; determine multiple intensities respectively associated with the multiple second portions of the laser beam; transform the multiple intensities into data that represents multiple measurement values of the multiple intensities; determine, from the data, if an intensity value of the multiple intensities is below a threshold intensity value; if the intensity is below the threshold intensity value, provide information that indicates an issue associated with the objective lens; and if the intensity is not below the threshold intensity value, provide information that indicates there is no issue associated with the objective lens.

The present disclosure relates to a defect inspection device including: an imaging part that captures an image of a first frame having a predetermined width and a predetermined length along a width direction and a length direction of a test object, respectively; an image division part that divides the image of the first frame of the test object captured by the imaging part into a plurality of second frames smaller than the first frame along the width direction of the test object; a brightness calculation part that measures a brightness value of each of the plurality of the second frames, and calculates a defect determination value of the first frame based on the brightness values of the plurality of the second frames; and a control part that determines a line defect existing along the length direction of the test object based on the calculated defect determination value of the first frame.
