Abstract
The invention provides a high efficiency coupling structure for extracting illumination such as fluorescent radiation from a chemical reaction vessel such as a cuvette. The cuvette is provided with a mirrored surface. An end cap for the cuvette includes a probe portion that exhibits total internal reflection. Lenses are provided in various embodiments that improve the light collection and directing properties of the end cap. A fast optical system for free space coupling of optical radiation emanating from a chemical processing cuvette that uses the end cap as an element is also described.
