Optical sample characterization facilitates measurement and testing at any angle in a full range of angles of light propagation through an optical sample, such as a coated glass plate, having a higher than air index of refraction. A rotatable assembly includes a cylinder having a hollow, and a receptacle including the hollow. The receptacle also contains a fluid with a known refractive index. An optical light beam is input normal to the surface of the cylinder, travels through the cylinder, then via the fluid, to the optical sample, where light beam is transmitted and/or reflected, then exits the cylinder and is collected for analysis. Due at least in part to the fluid surrounding the optical sample, the optical sample can be rotated through a full range of angles (±90°, etc.) for full range testing of the optical sample.

Exemplary optical scanner apparatus, method and computer-accessible medium for obtaining information regarding the sample can be provided. In certain exemplary embodiments of the present disclosure, the optical scanner, method and computer-accessible medium can utilize a container configured to hold the sample which is provided in a fluid. A light source can be provided which is configured to emit a light radiation to the container and the sample. Further, with an optic taper, it is possible to receive, taper and combine substantially parallel beams of an output radiation exiting the sample. The output radiation can be provided in response to an irradiation of the sample by the light radiation. Further, using a light detector, it is possible to receive and detect the combined tapered parallel beams so as to obtain the information regarding the sample.

An inspection device is provided. The inspection device includes a platform, a cage, a holder and an image capturing module. The cage is disposed on the platform, wherein the cage includes a first transparent side and a second transparent side, and the first transparent side and the second transparent side are not coplanar. The holder is disposed in the cage. The image capturing module captures a first image from the first transparent side, and it captures a second image from the second transparent side.

Provided is a microscope including: a chamber storing a solution in which a cuvette accommodating a solution together with a sample is immersed and that has an index of refraction identical to that of the solution; an immersion objective lens being placed outside the chamber and collecting light from the sample; a camera acquiring an image of the light collected by the lens; a targeting section moving the lens in a direction along a detection light axis thereof; and a movable stage supporting the cuvette in the chamber so as to be movable in at least a direction along the detection light axis. Each of the cuvette and the chamber has a transparent section that can transmit light coming from the sample. The lens is placed so as to face the transparent section of the cuvette with the transparent section of the chamber interposed therebetween.

The invention relates to a device for examining samples (1) in a liquid (5), comprising a movable shaft (2), to which the sample (1) is fastened, and a cuvette (4), wherein the device further comprises a bath (3), which surrounds the movable shaft (2), and wherein the bath (3) is fillable with the liquid (5), the movable shaft (2) is configured to receive the sample (1) at the upper side (24) thereof, the movable shaft (2) reaches into the cuvette (4) from below, wherein said cuvette is open at least toward the bottom and configured to be immersed into the liquid (5) in the bath (3) with the underside thereof, and, moreover, means are provided to generate a pressure difference between the interior of the cuvette (4) and the region outside of the cuvette (4) such that the fill level (21) of the liquid (5) in the cuvette (4) is adjustable. Moreover, the invention relates to a method for examining samples (1) in a liquid (5).

An inspection cuvette for the optical inspection of an ophthalmic lens comprises a hollow cuvette body defining a cavity for receiving the ophthalmic lens and an inspection liquid, a transparent bottom having a concave upper surface delimiting the cavity at a bottom end thereof, a handling channel having an inner circumferential channel wall and a longitudinal channel axis. The handling channel further has an access opening at a proximal end thereof and is connected to the cavity at a distal end thereof. The inspection cuvette further comprises and an inspection window comprising a flat lower surface delimiting the cavity at an upper end thereof and facing towards the concave upper surface of the transparent bottom. At least that portion of the inner circumferential channel wall which is arranged above the flat lower surface of the inspection window when the cuvette is arranged in an inspection position is round.

Described are various embodiments of a refractory lance assembly and a composite refractory lance. In one embodiment, a refractory lance assembly is provided that comprises: an immersion tube having an immersion tip immersible within a melt and an extension tube coupled at an opposed end thereof to form a longitudinally extended composite tube therewith defining an optical path therein, wherein said longitudinally extended composite tube is injectable, in use. with an inert gas to form and probe an immersed melt surface. The assembly further comprises a shroud longitudinally encasing the composite tube and injectable with inert gas to mitigate fluid contamination of the composite tube and immersed melt surface.
