Method and apparatus to illuminate sample and containing vessel in a light scattering detector

摘要

A method and apparatus for the illumination of a sample are disclosed. An imaging illumination light source is directed to pass through an absorbing/transmitting structure in order to illuminate the sample and any containing vessel. A diffuser may aid in properly dispersing the light from the imaging illumination source. A light sensitive detector such as a camera records an image therefrom. The beam from a light scattering source is directed through the sample and any containing vessel, and upon exiting the sample/vessel, impinges upon the absorbing/transmitting structure selected to absorb at the wavelength of the light scattering source. Scattered light from the sample is collected by a photo detector. Methods of use for the novel lighting system are also disclosed.
