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.
