Abstract: Embodiments of antimicrobial weight plates with an antimicrobial copper alloy, preferably a cuprous nickel alloy, preferably the alloy contains approximately 91% copper and approximately 9% nickel. A first embodiment having a core weight plate and one or more weight plate handles coupled in a circumferential edge of the core weight plate, the weight plate handles with antimicrobial grip surfaces are each formed from the antimicrobial copper alloy. A second embodiment having a core weight plate in a shape of an annular disk formed from an antimicrobial copper alloy. A third embodiment having an antimicrobial weight plate including two antimicrobial weight plate surfaces, each including the antimicrobial copper alloy, and a core weight plate sandwiched between the two antimicrobial weight plate surfaces. A fourth embodiment having a core weight plate, and an antimicrobial copper alloy coating thermally sprayed on to the core weight plate.

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.
