Abstract: An illumination apparatus for configuration with spectro-fluorometer system includes at least one light emitting diode (LED), a collimator, and a light guide. The at least one LED may be configured to emit light including a first beam-width angle. The collimator is optically coupled to the at least one LED. The collimator is configured to collimate the light emitted from the at least one LED to form a collimated light beam including a second beam-width angle and a first cross-sectional illumination intensity profile. The second beam-width angle may be less than the first beam-width angle. The light guide may be configured to alter a cross-sectional area of the collimated light beam and output a substantially homogenized light beam including a second cross-sectional illumination intensity profile with greater uniformity than the first cross-sectional illumination intensity profile.
