Abstract: A system and method that redistributes light from a light source. The controller can redistribute light to make an irradiance profile of the light source more uniform or make the irradiance profile match a fluid flow profile. The irradiance profile may be controlled by modifying light leakage from a plurality of waveguides or changing the light-directing properties of reflectors and/or lenses.

Abstract: A macroscopic fluorescence illumination assembly is provided for use with an imaging apparatus with a light-tight imaging compartment. The imaging apparatus includes an interior wall defining a view port extending into the imaging compartment to enable viewing of a specimen contained therein. The illumination assembly includes a specimen support surface sized and dimensioned for receipt in the imaging compartment, and oriented to face toward the view port of the imaging apparatus. The support surface is substantially opaque and defines a window portion that enables the passage of light there through. The window portion is selectively sized and dimensioned such that the specimen, when supported atop the support surface, can be positioned and seated over the window portion in a manner forming a light-tight seal substantially there between. The illumination assembly further includes an excitation light source, and a bundle of fiber optic strands having proximal ends thereof in optical communication with the light source. The distal ends of the strands terminate proximate the window portion of the support surface. The distal ends each emit a respective beam of light originating from the light source which are then collectively directed toward the window portion and into a bottom side of the specimen wherein the diffused light passes there through and exits a topside thereof for receipt through the view port to view the fluorescence of the specimen.

Abstract: A postacquired spectrophotometer, for use with a sample and reference. The spectrophotometer has a filter unit, defining an axis of movement, and pluralities of designated sites and dark sites disposed in uniform relation to the axis. The designated and dark sites are disposed in alternation. Alternating designated sites have apertures and filters covering the apertures. Further, a main member, coaxial with the filter unit, has sample and reference beam paths, which are intersected by the sites. The main member has disposed, in operative relation to the actuators, an actuator sensor, which generates an integration actuator signal upon alignment with each integration actuator and a clamping actuator signal upon alignment with each clamping actuator. Moreover, a drive continuously moves the filter unit relative to the axis and beam paths. Further, a light distribution system directs light separately from the sample and reference to respective beam paths, and then to a detector, which produces a detector signal responsive to light received. Finally, means for processing the signals is provided, including a clamping circuit, integrators, and a demultiplexer.

Abstract: An analyzer measures properties of multiple chemical samples, and includes an optical filter element having a long axis and positioned at a location where simultaneous multiple light beams, corresponding to the chemical samples to be measured, form a diffuse light spot elongated along an axis which is substantially aligned with the filter element long axis. The analyzer also includes a light source, filter means incorporating the filter element for transmitting spectrally selected portions of the light beams, sample cell means for exposing each sample to its associated light beam, and detector means for detecting the light beams after modification by the samples and after transmission by the filter. In a preferred embodiment, optical fibers carry the light beams to and from the chemical samples.
