Abstract
The present invention provides an optical transmission device, comprising a chamber having a light input into the chamber, and having a first port allowing light to pass out of the chamber, and comprising internal surfaces where at least a portion of the surfaces is diffusely reflecting, and where at least a portion of the one or more surfaces is specularly reflecting, and where the light input and the first port and the one or more surfaces are configured such that substantially all light entering the chamber via the light source within a first predetermined aperture must encounter the diffusely reflecting portion before exiting the chamber via the first port within a second predetermined aperture. The invention can provide substantially homogenous light transmission, both as a source of light for optical systems and as a collector of light from a sample.
