Optical coupling gel for flow cytometry apparatuses and the like.

摘要

An apparatus for determining one or more optical characteristics comprises a transparent liquid flow chamber and a source for providing a beam of light. A lens is positioned adjacent to the flow chamber for focusing light. A layer of gel at the interface of the flow chamber and the lens provides a refractive index matching medium to facilitate light transmission between the lens and the flow chamber. This apparatus preferably includes at least one light detector so that the detected light may be used to determine one or more optical characteristics.
