A spectrometer or multiple wavelength absorbance detection method and apparatus providing improved accuracy for an array of measurements at different wavelengths. The spectrometer utilizes a multiple wavelength illumination system with an array of independent detectors with different pathlength cells, where each cell is illuminated with predominately monochromatic light after separation by a light dispersing element. Each sample cell has an optical pathlength, optics and photodetection device that are optimized for its particular wavelength to accurately measure absorbance through an expected substance.

A water disinfection system includes a housing having a plurality of risers therein for directing independent columns of water from a manifold at the bottom of the housing. An ultraviolet light source is disposed above the risers to treat the water flowing therein. The UV light source may also be in the form of a fiber optic system (FIG. ) or a mercury arc lamp including a parabolic reflector . Each of the risers can also include notches (FIG. ) for inducing turbulence to the water flowing thereover in order to ensure that all of the microorganisms receive ultraviolet light. The water flow rate and the light intensity may be adjusted to accommodate different levels of water contamination.

An ultraviolet (UV) disinfection system and method for treating for treating fluids including a configuration and design to function effectively with at least one UV light source or lamp that is not submerged in the fluid. The UV light source is positioned outside the fluid to be disinfected via exposure to at least one UV dose zone outside the fluid being treated wherein UV light is projected into the at least one dose zone. The UV light source may be presented in a vertical riser configuration, wherein the UV light source is positioned above the fluid to be treated and projecting a UV dose zone downward toward and into the fluid to be treated, with the fluid moving upward toward the UV light source.

At least one interface plate is used to provide a surface zone for UV disinfection above the fluid and to provide additional treatment means for balancing pH, affecting effluent chemistry, and the like.

An optical fiber illumination system comprises a segmented reflector that efficiently couples energy from a lamp into a plurality of optical fibers. The segmented reflector offers the ability to improve the coupling efficiency by utilizing the cross-sectional area and numerical aperture of more than one optical fiber at the output of a reflector. Also this reduces the energy collected by a single fiber, and can be useful in preventing damage created by the source intensity. In practice, a source lamp is placed along a reflector axis. The reflector is specifically designed for a particular style and type of lamp, and is designed to collect as many rays from that lamp as possible. In a preferred embodiment, the reflector comprises four segments. Each of the four segments forms a distinct focus. In this embodiment, a plurality of lightguides, preferably optical fibers, are placed at the output of the reflector, one each at each focus of the respective reflector segments, with the longitudinal axis of each optical fiber substantially parallel to the axes of the reflector and the lamp. Assuming radial symmetry, each of the four fibers will collect substantially the same amount of light energy, and will transmit this light energy to an end device or user.

Segmented reflector for coupling an extended illumination source to N fiber elements

A lightguide illumination system is disclosed for providing more improved and efficient technology for capturing light from an extended light source having a relatively high aspect ratio, and coupling that light into a plurality of lightguides.

In the preferred embodiment, a plurality of interleaved trough reflector segments are employed to segment the length of the light source. This enables the coupling efficiency of the total system to be greatly improved.
