ABSTRACT:
A specimen support for optical observation or analysis is disclosed. The support comprises a disc-like member composed of a rigid material and having a plurality of holes extending therethrough, preferably in a screen of substantially equal-sized holes. When analyzing a liquid specimen, the disc is dipped in the liquid and the surface tension of the liquid will cause the liquid to bridge or span the holes. The support is then placed vertically in a tray or holder and exposed to an infrared beam that passes horizontally through the holes to generate an infrared spectrum.
