MULTISPECTRAL IMAGING SYSTEM

摘要

The invention features a multi-spectral microscopy system for illuminating a sample with light of a selectable spectral content and generating an image of the sample in response to the illumination. The multi-spectral microscopy system includes a multi-spectral illuminator that provides output radiation having the selectable spectral content. A preferred set of optical arrangements for the multi-spectral illuminator generates the output radiation so that the spectral content of the output radiation is substantially uniform across its transversal profile. Furthermore, the multi-spectral illuminator can include monitoring optics and a corresponding detector array that independently monitors the output in each spectral band of the radiation produced by the multi-spectral illuminator. The monitoring provides calibration, feedback, and/or source aging information to insure robust and reliable performance for the multi-spectral illuminator. The multi-spectral microscopy system also includes a microscope which illuminates the sample with light derived from the output of the multi-spectral illuminator, and beam modifications optics, which modify the output from the lamp prior to the microscope and fully exploit field of view and resolution of the microscope.
