Abstract: 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.

Abstract: Optical sample characterization facilitates measurement and testing such as transmittance or reflectance at any discrete angle in a full range of angles of light propagation through 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 having a refractive index matching the refractive index of the cylinder and coated plate. An optical light beam is input normal to the surface of the cylinder, travels through the cylinder, then via the index matching fluid through the coating, the coated glass plate, the fluid, the other side of the cylinder, and is collected for analysis. Due at least in part to the index matching fluid surrounding the coated plate, the plate can be rotated through a full range of angles (±90°, etc.) for full range testing of the coating.

Abstract: Disclosed herein is a system for producing a composite prism having a plurality of planar external surfaces by aligning and bonding two or more prism components along bonding surfaces thereof, the system includes: an infrastructure configured to bring the bonding surfaces of the first prism component and the second prism component into close proximity or contact; a controllably rotatable mechanical axis configured to align at least one first surface of the first prism component and at least one second surface of the second prism component; a light source configured to project at least one collimated incident light beam on the at least one first surface and the at least one second surface; one or more detectors configured to sense light beams reflected from the first and second surfaces; a computational module configured to determining an average actual relative orientation between the at least one first surface and the at least one second surface based on the sensed data and if a difference between the weighted average actual relative orientation and an intended relative orientation between the at least one first surface and the at least one second surface is below an accuracy threshold, determine a correction angle for the controllably rotatable mechanical axis, wherein one or more of the prism components are transparent or semi-transparent.
